I have my Asterisk server set up and everything is working (mostly) fine. One small issue I'm running into is that every so often, instead of Asterisk showing the incoming call from (for example) number "555-1234", it will show it as "SIP 1". "SIP 1" happens to be the the ID I've assigned to this SIP trunk in my provider's web platform (ie: my trunks are managed from my provider's web platform, and the platform requires me to have a "User" which is basically my phone number, and a an "ID" which is basically an identifier for the trunk.) Without doing IP lookups, I'm almost 100% sure that this is happening on calls coming in from callers that use my same SIP provider. Looking at the Asterisk logfile the most relevant information I can see is this: code:I'm guessing this is probably a fuckup on my provider's side which is probably processing SIP invites in the worst possible manner. Is there any setting in Asterisk I can add that will make it ignore the Caller ID and just use the number? Edit: just so it's clear, "5551234" is not my number, it is the caller's number. "SIP 1", however, is the ID of my trunk in my provider's web platform. dpkg chopra fucked around with this message at 22:03 on Jun 30, 2016 |

Does anyone have phone service from Time Warner Cable? Right now we have an Arris box with what looks like a centronics connector going to a 66 block. It has a single yellow ethernet port that I haven't been able to find anything about.

They are usually for phone use only, the Ethernet port will often be disabled or only for local management.

Anyone ever seen a phone, specifically Shortel, stop working over the handset but work over the speaker? I figured PoE but nope, and apparently Shoretel says it's a QoS issue. Lo and behold QoS is misconfigured, but could that really cause some bizarre issue with handsets vs speakers?,

Any recommendations for full hosted VoIP? 4 locations, NYC, LA, London, Paris. Employees per office is 30, 10,10, 10 in that order. We're looking for iPhone/Android app/Windows/OSX softphones only so people's extensions follow them. In NY we'd need a receptionist console. I honestly have no idea where to begin. We're rolling out Google Apps so I'm kind of thinking of picking the best option per location and just telling people to use Hangouts for inter office calls (like our current extension VTL setup on an ancient 3com NBX setup).

How prolific are hosted VOIP products with built in user monitoring suites and reporting interface? There's a bit of a shitstorm brewing since despite hating everything about our old host they want its features back. Before everything was cloud/software based with the hardware just being an end-point of sorts, there would be a CRM applet staff would log into to make calls and control their user state (Ready, Out to lunch etc) which would feedback into an integrated reporting interface, but it didn't quite properly integrate with our IP phones leaving some janky issues. Now the host we have now is more hardware based where the phones fully connect to the service, however there is almost zero user state control and minimal reporting (They would have to use the softphone interface to control their state). Despite the main goal from the big cheese to save money (previous host was hideously expensive) a main department is claiming they literally cannot function without the previous functionality. I'm just honestly curious how common functions like these are and if it's more of a "You get what you pay for" kinda deal.

This is probably a long shot, but is there anyone out there who has hooked up a Yealink phone with a VPN? I'm having a hell of a time getting home working VOIP operations up and running, and my hope was using these phones since they support OpenVPN as recommended by our VOIP host... but they can't actually assist with the setup beyond configuring the phones. I haven't had much time to spend on this but I spent the last hour of the day setting up the OpenVPN hyper-v appliance, but I'm assuming I need to at least get an external IP/domain to route through and open up relevant firewall ports, then bundle the client.crt/client.key/ca.crt into a .tar to upload to the phone? I mean I've hosed around with OpenVPN on a raspberry pi and my mobile phone, but that was a whole lot simpler in comparison.

I haven't done it yet but that is near the top of my to-do list to play with. I have OpenVPN set up at my house and a few examples of both the T2x and T4x lines so I might tinker with it this weekend if I get bored. Any specific questions or just looking for an example config to follow? edit: Unrelated FYI, if you have a Polycom phone with a MAC that doesn't start in 64167F rather than 0004F2 make sure you're running 4.0.10revD or newer.

Just kind of a bare-bones guide really, my google-fu lead me to a few guides but they all slightly differ in some way. At the very least I've got a VM set up but not the connectivity, and the keys etc I think need generating but the web interface is a bit vague so I'm guessing the meat of things need to be done in CLI. With the rasp pi I basically just ran the http://www.pivpn.io/ command, generated a user, fetched the .opvn key file and slapped it onto my mobile for the OpenVPN client app to read.

I love Yealink phones. That said, their VPN client is 100% garbage. Don't bother trying to get it to work. I've got a small business client I still support who wanted a phone at home. They're 100% google apps, so everything is in the cloud except for their PBX, which is an old on-site asterisk box. I set up a Yealink at his house using a raspberry pi with an extra USB nic as his openVPN endpoint and just routed the phone through the pi, works fine. Haven't talked to him in 8 months so it's either still working or he's dead.

If they were T2x phones they're not worth all that much, though they're still decent if ugly phones. T4x are my current favorite line of VoIP phones on the market, especially the new T4xS models.

Audio is about 97% the same on headset or handset, but Polycom's speakerphones are still worlds better than the competition. My Yealink T46S is my favorite day-to-day phone right now but if I know I'm going to be using speakerphone for something I switch over to my Polycom VVX400. Which one are you calling brain dead? Yealink's is a pretty straightforward plaintext config file and Polycom's is XML Polycom's parser is a bit weird and the format of their example configs takes advantage of that weirdness, but they are valid XML that you can both generate and parse with standard XML libraries.

Polycom's XML format is bad. They made it with the intent of having a singular config that applies to all poly soundpoint phones, but it doesn't work that way. I still end up with a ton of tiny fixes here and there for models and firmwares where the customers BYOD. Also the VVX series is kind of a joke, their android fork is kneecapped, and their companion software is barely functional if you can keep it connected to the deskset at all. wolrah posted:Audio is about 97% the same on headset or handset, but Polycom's speakerphones are still worlds better than the competition. ... and then there's Cisco.

Has anyone made the jump from Asterisk to 3CX, or more accurately, from Elastix 4 to Elastix 5? Is 3CX needs-suiting for your setup? I toyed with 3CX in a VM and considered migrating to it, but I was actually a little put off by how simple and configuration-free it was compared to Asterisk. By the way, there is no problem with my Asterisk config. The uptime is measured in months and only changes when I periodically have CentOS update. Asterisk also does everything I need it to sufficiently. But the interface, even in Elastix is horrendous, and my job may not always have someone like me who wants to mess about with software as complex as Asterisk. Which is why I wondered if 3CX would be a nice move towards a more simple setup?

Out of curiosity - I run a PBX that does accept remote SIP so people's cellphones can have SIP clients ring at the same time as their desk extension does, plus road warriors. Constantly getting bruteforce attempts on it, that fail2ban promptly blackholes. Anyone know what they're actually intending to do? Are these forwarders for tech support scams, shady calling-card companies or something? I'm trying to wrap my head around why anyone gives a poo poo about stealing VoIP when it's so cheap to buy it to begin with.

Most of the successful attacks I've seen on my customers have tried to pass international calls through our system. One of the times where my boss redirected the calls to his phone it turned out to be some calling card thing. The attackers had hacked some west coast dentist's PBX fully and were routing calls through one of his unused numbers out a trunk they had pointed at my customer's insecure system, where they were then having it dial a number in some Pacific island country I don't recall where they could then dial through to their actual destination. Our best guess is it was a fully automated attack, because our system plays an audio error message rather than just rejecting the call so it would have looked like the international call succeeded.

As mentioned before they may be looking for open registrations or easy to guess ones (usually I don't see them bother to try and register they just place calls), or an agent that's open that will permit their call to complete somewhere, if it does , then try often seem to try and get their calls to go through to a mailbox or do something they can break out of. I would not expect anyone to be wasting their time dialing random extensions@ip trying to reach you for a scam but who knows. You can block attempts or just let them do nothing and fail out, I've never seen the scanning really get _more_ aggressive because something responded. If your PBX responds with what it is, then there is a shot they can exploit it. I installed Trixbox years ago and it was hacked in like ... an hour, just installing a Live CD to see what was up. BTW these things still come by in H.323 as well as SIP.

I got nailed once when I first setup VoIP - although it was some idiot adding an easy-to-guess extension password rather an exploit. Getting fail2ban working on the logfiles properly took some doing but it's nice seeing it shut attacks down fast. There was some sort of pager/notification callback exploit on an actual analog PBX I had the misfortune of dealing with once, that was exciting. I can't even remember what the hell it was, except expensive as poo poo and dumped on my lap with no service contract, documentation or support. No backoff so they hammered PIN extensions until they got in and setup some forwarding. The $10k phone bill cost a lot more than they saved not getting a support contract for it. Charter/spectrum has started molesting SIP traffic, has anyone else seen that? The packets arrive, but they're rewritten to come from some not-us address, then it fails to forward the RTP to me. I'll contact support about it but it would be nice to have something specific to tell them other than "My VoIP with not-you doesn't work anymore". I "fixed" it by using a third-party VPN, but that adds audible latency.

Here's something we're dealing with right now; We have 3 domestic SIP circuits through our LEC, Electric Lightwave. These are SIP connections only, no internet access on the 5 meg circuits. About 5 weeks ago I get a call from their fraud department that they were seeing a bunch of calls being made to the Seychelle Islands at 6pm at night. I told them to turn off international calling and I'd investigate when I got home 3 hours later. Turns out someone screwed up the circuits and opened 2 of the 3 up to the internet so our SBC got used as a relay. Yes, it was bad on me to not have backup firewall rules in place, but please don't randomly open my poo poo to the internet. Turns out the tech didn't know how to shut down international calling so he just let it go for 3 hours. We racked up 14,000 minutes of international calls for about 12k. We're still fighting with them over the bill.
