2024.05.13 06:07 AntelopeInfinite7695 Trouble with VoIP Calls

Hey everyone,
I'm experiencing some difficulties with VoIP calls on our network, and I'm hoping to get some advice or insights on how to resolve them.
We have a Cisco IP phone and a Grandstream GRP2601 IP phone set up on our network, both using the same VoIP service provider and trunks. Our VoIP service provider typically only allows A-law (PCMA) and μ-law (PCMU) codecs, while disabling all other codec options.
However, when I attempt to make calls with both PCMA and PCMU codecs enabled on the Grandstream phone, the calls fail to connect entirely. There's no audio in either direction, and the calls cannot be established. Interestingly, the Cisco phone operates flawlessly with both codecs enabled.
The GRP2601 web setup also comes with several others codec option which is G.723.1, G.722 (wide band), iLBC, G.726-32, Opus, and G.729A/B, and when I try each one of this codec either by itself or with any combination with the others (except using PCMA & PCMU together) the call can pass through but without ringing tone, and the caller voice can be heard on the callee's end but the voice of the callee's cant be heard by the caller.
I've confirmed that SIP ALG (Session Initiation Protocol Application Layer Gateway) is disabled on our router, so it doesn't seem to be the cause of the issue.
Has anyone encountered a similar problem before? Is there a specific configuration or setting that I might be overlooking? Any advice on how to troubleshoot or resolve this issue would be greatly appreciated.
Thanks in advance for your help!

2024.05.09 18:07 Mother_Construction2 New to VOIP, will this concept work?

I have a landline and I want to dial and receive calls remotely.
Will a VOIP gateway (eg. Cisco Linksys PAP2T) plugged into my landline (RJ11) work with Asterisk so I’m able to dial and receive calls remotely on my cellphone?
I’ve used 3CX as VOIP for multiple cellphones, but no experience dealing with RJ11s.
Thanks.

2024.05.07 19:35 Plainzwalker Crestron/Biamp room with Cisco codec issues dialing Teams conference calls

So have an odd issue at a client site that I can’t seem to find the source of.
Crestron control, biamp Tesira for audio and VoIP calls, Cisco codec for video calls.
If the client calls from the room to Teams conferencing system the # isn’t registered when pressed during these calls. Biamp sees it being pressed, it works during normal calls, WebEx, Zoom and other teleconference calls but not Teams.
Any suggestions? They have multiple rooms, some have no issues at all, some have intermittent issues. I am 99.9% sure it’s not equipment or code issue since the biamp registers the # symbol and all other services don’t have an issue.

2024.05.06 16:16 curvedelk How to configure all file systems as read only (TP-Link MR 200 - OpenWRT v 22)

I have installed asterisk to the router and configured it to be a voip phone server for 3 cisco 7911 phones . It will act as a glorified intercom system for a small organisation once installed . It is currently working flawlessly. I don't need it to write any log files or anything else for that matter. I am hoping that it will be a set it and forget it kind of thing. The main motivation behind it is that i did have a router with a not so great nand chip that got worn down quickly after installing openwrt on it

Hiya, I'm currently trying to get into VoIP and I was wondering if there are any VoIP training/ testing applications available.
Currently on Cisco Packet Tracer for the basics and getting the concepts shaped in my head to visualize in the future.

2024.04.29 18:35 nice_crocs Need a switch recommendation if possible

Hello all, I'm sorry if this has already been asked before I am trying to figure out a switch that would be best for our company to start to implement moving forward. I should preface with we do not have a dedicated networking person, and I am by no means a network admin.
Currently we have 15+ locations that have a topology where the ISP comes in, hits a dmz from there it hits a managed switch from the MSP, but after that we have our own L2 switch that all of our clients connect to. We currently have a hodge podge of HP, netgear and cisco switches between the locations that were setup well before I got here.
Unfortunately we have to keep the DMZ and other switch, but we are looking to uniform the L2 switches that we have to manage and looking for recommendations on brand / model. We would prefer for the devices to have a cloud management portal or something of that nature if possible similar to ubiquiti / meraki. We looked into ubiquiti but the issue is needing the USG at every site to have the cloud management, but all we need is the switch and something that allows visibility to make networking issues easier for all of our staff that handles them. We were looking to switch to Zxzel switches but after looking through this sub we decided against that.
The only requirements we have are to allow multicast traffic for voip paging and 48 port poe with a minimum of 350W if I'm not mistaken.

2024.04.29 04:55 AntelopeInfinite7695 Seeking Resources for Learning VoIP as a Beginner in a New Job

Hello everyone,

I recently started a new job as a VoIP engineer with limited prior experience in the field. Although I was upfront with my employer about my background and they agreed to train me, the training hasn't started yet due to the absence of the senior engineer who is supposed to mentor me. Meanwhile, I'm eager to learn and start contributing.

In my new role, I'll be working primarily with FreePBX and Asterisk. While I have some theoretical knowledge from college labs using Cisco IP phones, I'm finding it challenging to bridge the gap to real-world applications.

Could anyone recommend any free resources, online courses, or reading materials that would help me get up to speed with the basics of VoIP, particularly focusing on FreePBX and Asterisk? I'm looking for anything that would help me understand the fundamental concepts and handle basic tasks.

Thank you in advance for your help!

2024.04.26 17:24 SmoothRunnings FS S3900-48T6S-R switch

We have 3 x S3900-48T6S-R switches in our environment, when we got them we didn't have much use to be setting up VLAN's as we don't use a VoIP system or anything fancy, the 3 switches help connect our desktops and printers to the other two main switches.
Now that we are looking to separate out parts of our network but keep everything together I have having a tough time wraping my head around the process to setup VLAN's on these switches. We want to setup VLAN 10 for our all our switchnig gear and give two computers (that reside in my office) access to be able to manage them. So I go to the L2 Configuration option in the WebGUI and switch the mode from Access to Trunk, then add VLAN 10, there are two other options Untag or Not, and Allow or Not. I thought the Untag or Not would mean the VLAN / Port would either be untagged or Tagged and weather it would be accessible or not. There is no real good explaination in the configuration guide. Either way when I turn off Untag or Not on VLAN 10; VLAN 10 is not accessible. When I look through the other options there doesn't seem to be any option to tag VLAN 10 on any of the switch ports, and when I check the CLI config it only shoes VLAN 1 is untagged (switchport trunk VLAN-untagged Range) on every port.
If I try to add a switchport trunk VLAN-allowed Range 10 to the port all the VLAN 1 traffic stops working all other.
On our Cisco SG350X switch it shows everything correctly in the WebGUI, all the ports have VLAN 1 untagged, and the other VLAN's tagged with the switch mode being in Trunk mode.
So I am not sure how to set this up correctly using the FS.com thinking...Can someone help me get my head wrapped around this?
Thanks,

2024.04.26 05:21 -S-J- Getting back in the field / Comp Tia

My apologies in advance if I'm posting in the wrong area.
Hoping to get some feedback here to better evaluate my options and see if others have been in a similar position and how you went about it. Again, I apologize if this is the incorrect place.
Looking to go back into the I.T field after stepping away for 2 yrs to take care of a family business and affairs/drama. To provide some brief context about myself I'm in my late 20s with a degree in Cybersecurity & Business Administration. I interned at a well known MSP in the area and was quickly hired on after finishing my internship and graduating.
For the next few years I worked directly below the owners of the MSP and quickly expanded my knowledge base thanks to their mentorship and incredible hands on experience they were willing to provide and their decades of experience. I learned anything from Domain Server management/AD to Exchange Servers, anything migration related for Servers, Office365 to Gsuite migrations, powershell script solutions, websites, office 365 admin, SharePoint management, RDS, VOIP, CCTV, Cisco Meraki, Ubquti to name a few I understand I'm forgetting to list alot well more then alot here but I'm hoping this helps provide some context.
At the time I was looking to build my portfolio of comp Tia certifications however, at this point I was fortunate to show my understanding and take on many clients and the owners really didn't care what I had on paper which I was grateful for.
Which leads me to today where I'm looking to get back in, and certs look to be a must which I completley understand. Where would you recommend starting on the cert platform? What's worth getting and spending money on and what would you consider a waste of time? I see some of these are "stackable" as well.
Unfortunately, I cannot go back to working for my old job as the owners have since sold the company. Otherwise I would in heartbeat due to the excellent work environment.
Any feedback and guidance is greatly appreciated!

I read the whole subreddit, how'd I do?
Before I get roasted: I know the UPS is up, and I know the SAS array isn't racked. All things in good time.
Proxmox on the ThinkSysytem (SR650 2x Xeon Gold, 128GB RAM, 10TB SSD), 12X12TB SAS drives in 3 24TB ZFS 2 pools, Dual WAN router (Fiber + 5G), Mikrotik smart switch, homemade patch cables, a bunch of weird keystones, and a Cisco ATA191. W
Proxmox is running OMV (Plex+Pihole+NAS), FreePBX (for the analog Kermit -> VOIP), ltsp PXE server for my gutted NUCs, and a VPN gateway.
There's a white gaming machine off to the right that's probably also going to get racked as a gaming server.
This is my setup in preparation for a move. I'm tired of building big distributed systems in my house, it's time to centralize.

2024.04.20 22:26 irishguy42 Diagrams and Scaling

I have a question regarding scaling and whatnot for drawings. My company just recently allowed me to explore using Visio instead of CorelDraw for doing schematics/floorplans/rack elevations/etc (we are a smart home A/V and network integration company).
With Corel, I'm used to just opening up a PDF sent to me and I'm on my way to editing and dropping in symbols, and I can't do that in Visio, so I'm cropping the PDFs and exporting the drawing portions of the prints as DWG files and inserting them into Visio (is there a better way to import PDFs? I did the SVG route and it doesn't work as well as DWG).
Sometimes this means I need to scale down the image to fit my paper (I'm using 24x36, when the drawing was on a 30x42 and I now have to scale it down to fit on the page. Is there a good way to calculate the scale of the new drawing? Is it good practice to just leave my Visio drawing at 1in:1in and then calculate the new scaled CAD drawing?
Example: I have a 24x36 paper and drop a floorplan from a 30x42 paper into it, and it's bigger than the 24x36 page. The scale from the floorplan I was given was 1/4" = 1'-0", and I ended up scaling the DWG to 1.25in = 1in. Is there a good way to easily calculate what the new scale for the DWG is? What I have done in the meantime is opened up the original floorplans in Corel, set the scale, and then measured a length. I then find that length in Visio, measure it (drawing is 1in=1in) and then use an online calculator to find the scale factor and then I write that as the scale in my Visio drawing (in this case, it was 1:60, so 1" = 5'-0"). Is there a better way to do this?
Also, when making my own stencils, is there a way in the shapesheet to set it up so that no matter what scale I set the drawing to in Visio, the shape will be the same paper size? As in, I have a stencil that is, for example, 1"x1" on the actual paper when I print it out (24x36). If I change the scale from 1:1 to 1/4"=1' to whatever else, can I set my stencils to not scale along with the drawing scale?
Sorry for the wall of text. I am looking up some guides, and would be happy with any resources you folks enjoy.
TL;DR:
  1. Best way to import PDFs? Using DWG insert now, tried SVG and didn't like it
  2. How to prevent my stencils from scaling with drawing and keeping actual page size regardless of drawing scale?
  3. Best way to calculate new scale if I insert a scaled drawing and need to size it down to fit my page size?
  4. Best learning resources?
Thanks!

2024.04.18 20:50 FischerPricex Automatic VLAN segmentation for non-company devices (i.e. smart TV's)

I have done some searching, but cannot find a solid answer on my particular situation. I am a Sys Admin for a healthcare facility with a full Meraki wireless/switch infrastructure (Cisco ASA firewall. Yes I know, old school). They have a flat topology for all of their wired ethernet connections. They then have a dedicated VLAN for guest wireless (internet only) as well as a few others for VOIP, etc.
They have discussed wanting to add port security for their wired connections (either 802.1x or AD MAC filtering for managed PC's). The tricky part here, is that they have dozens of Smart TV's in rooms that are wired in because they are in areas with poor wireless coverage. They want to keep these TV's wired in, without easily being able to identify which switch ports they are plugged into, while implementing port security for PC's only. The intended end result would be that when an authorized PC plugs in, they are placed on the internal network, and when a non-company device (such as a smart TV) plugs in, it gets joined to a guest VLAN with internet-only access.
I've found several solutions involving the use of splash screen redirection when a PC fails to present a certificate, but that doesn't work for something like a Smart TV (to my knowledge). What options do I have that don't involve going around to each TV and allowing the MAC address on the backend (assuming there are other options)? If that's what it takes, that's fine, just want to make sure there isn't an easier way.
Thanks!

2024.04.17 23:42 you_wut Dialpad and Voice edge

My S/O works for a small business that has a parent company in the same building. One uses Dialpad and the other uses Voice edge. They essentially want an end user using dialpad to also take calls from Voice edge. As you can imagine all they told me was they added that users “line” in assuming phone number to voice edge and now are having problems with incoming/outgoing and voicemails. Would this be a matter of setting up the VoIP phone to work with two cloud pbx services? Adding them to the phone and configuring it? I’m not versed in VoIP at all but do have basic networking knowledge dealing with some cisco equipment configuring routers/switches/firewalls for some basic homelab stuff. Any advice would be super helpful!! Thanks in advance :)

2024.04.16 15:44 sarosan Cisco Duo data breach at third-party provider

I realize this was yesterday's news but I didn't see anyone mention it on here. So, in case you missed it:
Cisco Duo says an unnamed provider who handles the company's SMS and VOIP multi-factor authentication (MFA) messages was compromised on April 1, 2024.
The notice explains that a threat actor obtained employee credentials through a phishing attack and then used those credentials to gain access to the telephony provider's systems.
The intruder then downloaded SMS and VoIP MFA message logs associated with specific Duo accounts between March 1, 2024, and March 31, 2024.
Source: BleepingComputer
Basically, Duo's third-party provider didn't bother to use MFA. The irony is killing me.

Trying to get the same exact issue fixed for 20+ years. Tech coming tomorrow. Never been elevated past first tier, still haven't. How to make sure tomorrow's visit is actually productive?
This is long, and I don’t quite know how to do a TL;DR that’ll do this justice, so please bear with me. This is a story that’s been ongoing since I was 11. I’m 32 now, still living with my parents to help care for my mother. I’ve become the keeper of this story, and my father has asked me to write out the full saga to present to our next tech (I really should have a shorter, summarized version to present, but this mess is hard to summarize, and I’ve already told every tech this story, to no avail), but I think I’ll present it here, as well. Our current spate of lengthy outages started yesterday (Sunday), and we have a tech coming on Tuesday, so I’m seeking input on how to make it a productive visit. Things to highlight in a summary for the tech would also be welcome.
I’ll start with our hardware: Gateway: Ubee DDW36C Router: Sagemcom FAST 5280 Set-top box 1: Spectrum 101-H Set-top box 2: Cisco Explorer 4642HDC Antronix VoIP Residential Amplifier VRA 500B
For over twenty years, pretty much ever since this house was built in 2002, we’ve been dealing with regular internet outages, as well as cable TV outages, pretty much the entire time (we would go elsewhere, but for much of that time, there were no other options, and we’re told the other options we have now are somehow worse). The internet outages are intermittent, and can range from under a minute (a daily occurrence throughout the year) to multiple days (the short ones were problematic, because Time Warner’s system only detected them if they lasted more than five minutes, though I think that’s no longer the case; I remember being encouraged by techs not to unplug our early modems—unplugging them did sometimes seem to kick-start things—to help make sure outages met the five-minute threshold). It’s worth noting that, as I recall, we got our first modem (one of the earliest Motorola Surfboards) while living at a different address, and it worked fine there. It wasn’t until we moved here that things started acting up.
The same applies to TV. With regard to TV, if we don’t have full outages, we’ll often lose audio on the TV and get a pixelated image. For the past ten years or so, we’ve resorted to watching TV with closed captions, because we lose our audio that often, and the caption signals are fairly resilient, often still getting through when the audio and even much of the video doesn’t. When it gets particularly bad, we eventually receive an STBH-3302 error from the set-top box. At least I think that’s the right number. Any other day, I’d remember the number, and I even have pictures somewhere… It might be 3802. We also got STBH-3101 yesterday, where we had TV but no internet, and the guide wouldn’t load…only for it to load a mini guide a few seconds later each time it threw the error (a mini guide I’d love to use more often, but which only seems to show up when there’s an error). We’ve also occasionally had things briefly go so haywire that the set-top box throws an error, saying service has been disabled, as though for non-payment.
The outages used to be seasonal, occurring almost exclusively in the summer, pretty much every year, primarily at peak load times for the neighborhood (morning, noon, after school, evening, etc.) and as the temperature increased (we’re in Ohio, so it doesn’t really get that hot, but it does warm up a bit). When Charter came in and took over Time Warner, they gave everyone a free bandwidth upgrade. At that point, our issues shifted to year-round, but still worse in the summer. That pattern is still holding, with fairly stable internet last night and this morning, but no internet for most of this afternoon.
A Spectrum tech parked outside our house a few months ago, having been mistakenly sent to our street for a job a couple blocks away. I took the opportunity to warn him of the sort of issues he might encounter in this neighborhood, and he informed me that another upgrade is coming soon, so we can expect our service to get even worse in the near future. I doubt that upgrade rolled out on a Sunday, though, so this seems to be separate.
I’ve seen the uptime graphs for the area a number of times in the past (though not recently). The infrastructure in the area appears to be incapable of supporting the load that is being placed on it. We and all of our neighbors take turns having internet. Whenever one customer on the graph would turn blue (up), another would turn red (down) at the same moment. There seemed to almost always be at least one or two outages, rotating their way from customer to customer. I don’t know if this is still the case, but it certainly was, for many years.
I’m not going to bury the lede (apparently this, and not “lead,” is the correct spelling, which I just learned recently, though I see spell check disagrees). I think I know what the root cause of the issue is, and I’m just going to put it right here, somewhat near the top. Within the past few years, we had a number of line techs pay our property a visit, having traced the problem of another customer a couple blocks away to our yard. They started digging, and found that when the heavy inch-thick coax cable that serves the small backyard boxes was laid, instead of taking up the excess slack in the cable, or cutting the excess out, whoever was laying the cable just buried the excess in a very small hole. Contained within a two to three-foot hole was an extra four to seven feet of cable, full of sharp bends, including at least one as sharp as ninety degrees. Both the outer black insulation and the inner white insulation had split open at the sharp bends, revealing the central conductor. I have pictures somewhere. They were stunned that it still worked at all. They cut out the damaged cable, spliced the ends together, and added another box to our yard to contain the splice. The fact that it still worked at all for that customer a couple blocks away leads me to suspect that we have the same problem as that customer, a damaged line that just barely works, and whoever laid that cable in such a poor manner here, did so all over the neighborhood, including with whatever line serves us (unfortunately, the one they repaired doesn’t serve us).
As it is, right next to where the line techs dug that hole, there’s an extra ten or twelve feet in a loop sticking up out of the ground, resting against the neighbor’s fence, that’s been there since forever, and boy is it ugly. Unfortunately, fixing it would probably require removing one or more of the neighbor’s trees, and possibly their fence, to make room for another box with a splice that would probably look worse than the cable alone, and the trees are home to countless birds, plus chipmunks. The phone company’s box is buried in that cluster of conifers at the corner of the neighbor’s yard, and the last phone tech that was here, replacing our line after a Spectrum contractor cut it, mentioned while crawling through the trees, that those trees should never have been allowed, but he’s a nice guy and isn’t going to have them cut down (I’m curious how the trees got there in the first place, because they were part of the original landscaping plan when the house was built, which was likely approved by the city). I don’t think the tree roots are the cause, because I believe our issues existed before the trees did. The giant loop of cable appears to be the same sort of cable that the line techs dug up. I kind of wonder if it was meant to be a spot for installing a box that was simply never installed, but it sure is odd, either way. Whoever laid the cable clearly didn’t know what to do with all their excess cable, and I’ll bet the same problem exists on the cable that serves our box. I’ve mentioned this to some of our techs, after explaining the origin of the extra Spectrum box, and they’ve just kind of expressed surprise and moved on, I think with a comment about how it would require a line tech to look into that (they may have misunderstood, and thought I was asking if the damaged cable that was repaired was serving us).
Our connection simply does not support DOCSIS 3.1. Only DOCSIS 3.0 (and presumably earlier) works here, that I can tell. With DOCSIS 3.1, a speed test will run fine, and a very small number of websites will work at acceptable speed (in hindsight, they may have been loading from cached data), but the vast majority of internet traffic is stuck running at a speed measured in Kbps (and I do mean lower-case b, as in bits), as low as twenty-five Kbps, from what I recall. With DOCSIS 3.1, our internet is literally slower than dial-up. We have a tech coming on Tuesday, and I am deeply concerned that, as usual, they’ll attempt to replace the modem, and just like last time, they’ll try giving us a DOCSIS 3.1 modem, and we’ll be without usable internet for the next month while they sort it out. Last time, they were eventually able to give us the very last model of DOCSIS 3.0 hardware still in circulation, a Ubee gateway (which the tech felt awful about giving us, saying he wouldn’t have given it to us if he had anything else). That was a number of years ago now (our internet since then, while very unstable, hasn’t had the prolonged outages necessary to merit the hassle of a service call, that never actually fixes anything). I doubt Spectrum still has DOCSIS 3.0 hardware available, so at the very least, this whole issue of not being able to use DOCSIS 3.1 has to finally get fixed. We’ve used two or three DOCSIS 3.1 modems (though one or two of those were only for a few minutes, during a service call), so I do believe it’s a compatibility issue with h DOCSIS 3.1 and not just a bad modem. I suspect we just have too much interference, probably from a damaged line, for it to work.
Of course, the DOCSIS thing has me thinking… Our newest set-top box of course includes some sort of modem for its IP-based functions. I wonder what DOCSIS version it uses? If it’s using 3.1, are we just getting lucky with having its communication fall under the category of “stuff that just happens to work?”
We have never been able to get our issue elevated beyond first-tier techs. The closest we ever got was when a higher-tier tech tagged along with two others, as part of providing training. Replacing the modem seems to temporarily fix, or at least improve, our issues, often for as little as a month (obviously, modems don’t actually go bad that quickly, but if I had to guess, fresh modems that are on-spec can handle our terrible signal just a hair better, just enough to be functional, and as soon as there’s any degradation, any minor drift out of cal, everything falls apart). I don’t know about Spectrum’s policy, but Time Warner required multiple service calls (we were either told it was two or three) within a thirty-day period to elevate an issue, and our issues always seem to recur just a few days outside that window. We did have a tech leave us a special number to use for our next service call, to request him, so he could come back and attempt to see things through to an actual fix, but of course, that time, things worked for a good while. Another tech, on his second visit (I think our most recent one, that gave us the DOCSIS 3.0 Ubee gateway, as well as the DOCSIS 3.1 modem before that), made a point of telling us that if we call back for another service call within a given period, they’ll send him back to troubleshoot further and basically clean up his own mess, and he encouraged us to do that, but things worked well just a little too long. We’ve gotten into this weird situation where we’re actually hoping for our stuff to fail more often and more severely…
The first tech who came to address our problems claimed that we had inferior wiring in our newly built house, and wanted us to pay to have the entire house gutted and rewired. We declined. The second tech remarked on how high-quality our wiring was, saying that it was quad-shield, higher quality than what Time Warner uses, and very difficult to cut through. He said this as he was attempting to cut through it to replace the coax connectors.
Every tech for the first five to ten years replaced every connector in the house, every time they came. We’ve lost much of the slack in our wiring as a result of the sheer number of service calls we’ve had (I’m sure a corporate financial person would be horrified to see how much has been spent on nonproductive service calls to our address), and can no longer afford to have the connectors replaced regularly. The connectors were being replaced so often (it seemed like it was almost monthly, at one point), that we ended up leaving the junction box in the master bedroom hanging out of the wall for the past fifteen or so years, to facilitate easy replacement, after getting tired of moving the dresser that resides in front of it. I’d really like to put it back in the wall, but of course, as soon as we do, they’ll want to replace the connectors again. They haven’t done it in a while.
Numerous techs have noted that the signal coming in from outside was “down in the dirt” (or similar), and that our modem was “screaming to be heard.” I’m including a screenshot of the signal while we actually do have internet, logs, and a couple signal screenshots from during outages. Outage ones are marked accordingly, though my writing is hanging off the top of Reddit's crop. Forgive the terrible handwriting, the annotation function on my phone wants to turn everything into a polygon, so I have to write really strangely to make it legible. I’m also not totally certain what things on the signal page can have security implications, so I probably censored some totally silly and unnecessary stuff, like the configuration file data. I can never remember what’s good and what’s bad, when it comes to the signal numbers. What’s interesting is that as our internet goes in and out from minute to minute, if memory serves, the numbers fluctuate wildly, showing a significant difference between when we do and don’t have internet. It’s also worth noting that our set-top boxes have always reported similar numbers to the modems, so again, the modems are not the problem. Unfortunately, Time Warner and Spectrum have heavily focused on the internet and the modems, because the TV signal just generally seems to be more resilient than internet, so the TV, visually and audibly, will often be fine or acceptable, while the internet is going out completely. Instead of looking for something that can affect both, they just drill down on the internet, and throw new modems at it, over and over.
Our modem logs, for the past twenty-plus years, have shown a steady stream of T3 and T4 time-outs whenever things are acting up. I’m actually a little surprised, because our current spate of outages seems limited exclusively to T3 timeouts. It’s happened before, but it’s rare.
Almost every tech for the first ten years or so claimed to go outside and “boost the signal” at the box in the back. We’ve since been told by one of our techs that there are no adjustable components there, and the signal cannot be boosted from out at the box. Having seen the innards of the box out back, there don’t appear to be any adjustable parts, such as potentiometers (I got a good look when a tech checked for water ingress, and I know my electronics reasonably well; my dad’s a senior electronics design engineer). It seems we were lied to. No one has attempted to boost the signal out there since. I will note that the contents of that box have never been replaced. A friend who used to work for Charter in another state (warehouse work, refurbishing set-top boxes and modems) claimed that they replace those every two years, where he is. That sounds excessive, but what do I know?
We did, however, have an active “signal booster” (I think the correct term is amplifier) installed inside the house a number of years ago by a baffled tech who was out of options, noting that they’re usually reserved for large commercial installations.
The line from the box out back to the house has been replaced twice, using the orange, silicone-filled (liquid silicone, I’m told), self-sealing cables. The most recent replacement was after a Spectrum contractor was laying new conduit and line down the length of our street, with zero regard for buried cables. Every time their excavator shut down and triggered an alarm for having hit a cable (which happened about once a minute), they just slapped an override button and kept on digging, even as they worked within three to six feet of an electrical transformer with buried lines. I don’t recall them marking anything before digging, either. They did substantial damage down the entire street, cutting numerous phone lines, coax cables, and at least one invisible fence. They probably did additional damage to Spectrum’s buried lines that we aren’t even aware of. They trenched straight through where the line techs had dug up all the damaged cable, as I recall. They also left a Ditch Witch in our yard over the weekend, poorly balanced over a trench, using the arm and bucket of their excavator resting on top as a counterweight to attempt to hold it in place. The Ditch Witch fell into the trench over the weekend (I mention this only because it speaks to their incompetence and poor safety practices). They cut our phone line, and when the phone company sent a crew to bury the replacement line, they cut our cable (and blamed us for not telling them we had cable, when they didn’t ask, and didn’t bother scanning themselves before trenching).
What we’ve been told is that the silicone-filled orange cables are prone to leaking liquid silicone into the connectors, and the connectors are supposed to be mounted horizontal to minimize flow of silicone. I doubt this is particularly effective, but nonetheless, the first orange cable installation made a point of doing so, mounting the connection horizontal on a board inside our basement (I question the usefulness of this, since the connectors in the basement are below ground level, so fluid pressure from being downhill is likely still going to be an issue, regardless of orientation). The replacement orange cable, installed after the mess described above, has a splice outdoors, above ground, with connectors in a vertical orientation. They retained a short section of the old orange cable for crossing the foundation into the house, so that’s an extra splice in the cable that probably shouldn’t be there, but I doubt it’s the source of our issues. If memory serves me, and I’m properly making sense of what I saw, it also looks like they grounded that outdoor splice by disconnecting the ground from our phone line, and using that, leaving our phone line ungrounded, so that’s fun. Just noticed that a few weeks ago.
The wiring in our house has been slightly overhauled, minimizing splitters, and adding a dedicated line for the modem coming from a three-way splitter in the basement (for two set-top boxes and the modem). I think there’s still a splitter on the line for one of the set-top boxes, with a cable that used to run to a Media Center PC back in the days of Windows Vista. That additional cable is currently plugged into the TV, mainly just as a means of terminating it. I have a quiet hope of someday setting up another media PC, as silly as that is.
We have one very new set-top box (one of the fancy ones with a radio remote—which frustratingly lacks a power button for just the box), and one very old (that I’m extremely surprised is still supported), to support an old TV that only has a coax input.
We have a Spectrum-supplied router, and somewhere we have a plethora of our own routers that we’ve pulled from service to appease Spectrum, when they inevitably tried to blame the routers.
When the techs stopped replacing the coax connectors with every visit, they switched to replacing the modem, so we have been through countless modems now, probably about one or more every one or two years. I’m quite tired of having techs throw a modem at the wall and see if it sticks, so to speak. It’s repeating the same experiment and expecting different results. The techs tend to agree that replacing the modems shouldn’t really be that helpful, and the modems don’t actually fail that often (though others have insisted they fail all the time). A number of them have suggested that our sudden improvements after service calls may be due to techs “cleaning out the cabinet,” supposing that the local cabinet may have been full of dust and overheating (hence summer outages), but…that doesn’t seem particularly likely, either.
I am at a loss for how to actually get these issues addressed, and how to hopefully prevent a DOCSIS 3.1 fiasco knocking our internet out for the next month. Is there anything in particular we should be requesting in advance of this upcoming service call? Obviously a DOCSIS 3.0 modem is something we could ask for, but I doubt we’d actually get it. I suppose a modem with accessible logs and signal data is also useful (we’ve had ones that hid all that, and boy was it a pain), but none of those things will actually help with fixing the underlying issue.
A friend once gave me the email address for the vice president of customer relations, but I doubt a message from an individual customer would get noticed, and that address is probably outdated by now. I’m not even sure how I’d condense this down to a reasonable length, anyway, so it would actually get read.
I realize I’m posting this late, for a service call that’s coming tomorrow. I fell asleep this morning as I was about to post this. Any input would be appreciated. Thank you!

2024.04.15 22:16 TmPulcreavi Late post - passed at 127 on 3/29

Very late to post here, but thought it was about time to celebrate.
On March 29, 2024, I provisionally passed the CISSP exam at question 127 on my first attempt. 3hr15m, no breaks.
To the individual who posted here as well, I owe you a debt of gratitude for encouraging me. You know who you are. Most importantly, thanks to my wife for a literal litany of reasons. My biggest doubter was me.
About me:
While I have never held a role within an actual security team, I do bring to the table 23 years of large enterprise network engineering and operations experience, including a hyper VoIP focus at a major telecom, with about 1.5yr as a manager at the telecom. MCSE from NT 4.0 timeframe (not current), CCNA from 1999 which I also let lapse as I didn’t feel like it helped all that much compared to the CCIE’s I was always working with (kicking myself now). Never had the guts to sit for that one.
Without a doubt, my professional experience played a major role in my preparation for this exam. Particularly, because I was able to apply my experiences directly with the concepts in each domain. HUGE.
I had my eye on this cert for many years, but felt cyber was a “pie in the sky” discipline that was difficult to get into. Over the years it’s importance has increased dramatically, not to preach to the choir here. So in my personal and professional growth trajectory, I knew I needed to finally go for this.
I started study several months ago in 2Q 2023. I used Destination Certification CISSP as my primary source (including their MindMap videos on Youtube), only incorporating LearnZApp on my phone about two weeks before my exam. I didn’t use any other study resources and I continued study up to the day before the exam to help keep my mindset in hopes that taking the exam would feel like just another study session. That worked for me.
I read through DestCert once over several months, very slowly, no pressure on progress. About 1 domain per month until I became more comfortable with the content. Once I scheduled the exam about 3 months prior to taking it, I read DestCert a second time, straight through with more highlights at faster pace. I wanted to read DestCert a third time, so I planned out enough days prior to exam day to cover all of my highlights (maybe 14 days, with one or two breaks). I went as fast as I could, considering this read through a “cram,” but I effectively read the entire text again. This was because the LernZApp questions had explanations that were not even grazed in DestCert material. That scared me.
I threw in one practice test on LearnZApp, and as many practice questions as I could muster having completed probably 500-600 questions. I made a 63% on my practice test, which I was fairly happy with given it was before my third read through of DestCert but did not pass at least 3 domains. My practice question pass rate greatly improved after some time and review of the domains in DestCert. The practice test was actually stressful to me, so I did not try that again. I felt the practice questions were a better resource for me, effectively teaching my brain how to answer the questions. THAT was a key thing to learn and can really only happen after trying many hundreds of practice questions. No doubt, there were many “micro lessons” as far as test taking skill learned over and over while reviewing the practice questions.
Test day:
Mistake - took the exam at 2pm and had a 1 hour commute with heavy traffic. Don’t do that.
Gamble - I showed up early, and the schedule allowed me to test early. Win! I wanted to get this over with. Be friendly and ask, you might get what you want.
Totally stressed out, I was expecting long complicated scenarios with long complicated options for answers which would eat away at my time. That never really happened. The questions were shorter and easier to understand than I anticipated (with a few exceptions), but many required some significant thought and analysis. That being said, never once did I think I was going to pass. Felt like I was going to fail the entire time. “Think like a Manager” was never read, but I relied on my experience and the phrase helped me get into the mindset (sort of a "that's all I needed to hear" kind of thing). In fact, knowing I had to potentially pick what I think would be the wrong answer (again, as a manager) probably contributed to my efficiency.
My strategy was to read each question on its own, consciously forgetting about the prior question. At about question 60, I resigned to failing, which I had resigned to well before anyways. I accept failure a lot, so not a terribly bad thing for me. Question answered after question answered, just kept going. Some tech, but nothing like a Cisco exam.
Exam suddenly ended after 127. I was shocked, so when it asked if I wanted to end the exam, I actually said NO! This was just to sanity check myself. Guess I am a glutton for punishment. ;)
Got checked out and the rest is history. Waiting on endorsement now.
I hope this helps encourage some folks, as I check this subreddit daily now. Challenge now is to get the language and buzz terms “on the tongue” for job interviews and eat some salary lunch, hopefully.
God be with you!
