What happens if you then add just one Digium phone? Does it, and all the other brands, work as normal? If yes, try adding one more, then one more - maybe you'll find one specific phone which is causing this problem. If adding just one phone causes the problem immediately, try adding a different one instead (in case the first one you added is the one with the problem). > >> The server remains operational and all other users/peers (not running > >> Digium phones) are up and running. > > > > You mean, all others at other locations, right? > > Yes, other locations are OK. This location will be "clogged" (or > "flooded"?) and unavailable. Can you run wireshark or similar on the router / firewall at this location, to see what SIP traffic you get going back and forth to the server at the time the problem occurs?

Sip debug and tcpdump didn't show any relevant information to solve the puzzle. What is relevant: do you see SIP traffic coming from those phones/location *AFTER* they are UNREACHABLE/kicked? Is a fail2ban involved ?

I'm wondering if some device is misconfigured and failing registration, which get spicked up by fail2ban, and the network's public IP gets blocked. > The server remains operational and all other users/peers (not running > Digium phones) are up and running.

[asterisk-users] Digium IP Phones UNREACHABLE after registration
I'm trying to solve a mystery for the last couple of days. I have a mix of D70, D50 and D40 behind NAT. Server is in a colocation, not a VPS. For several years, everything was working fine, no issues. A few days ago I started having problems at one particular site. NO CHANGES have been made to this office network - same router, switch and internet provider. No new equipment added or configuration changed (I only upgraded the firmware and asterisk trying to solve the problem). A few seconds after registration, the Digium phones will become UNREACHABLE. Right after that, the entire VoIP network (where the Digiums are located) will be also dropped - all other devices (non-Digium) connected will be kicked from the asterisk box. There are ObiHai, Yealink and Linksys at this location - all will be kicked. The server remains operational and all other users/peers (not running Digium phones) are up and running. Sip debug and tcpdump didn't show any relevant information to solve the puzzle. I also replaced the router (twice, different models and firmware versions), PoE switch and cable modem. No success. IP is dynamic but the provider will only change it once a year. Qualify=yes (or no) didn't fix. Removing the password (deny/permit IP) also didn't. Running Asterisk 13.20.0, firmware 2.6.2. Any ideas where I should dig further? -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?

Re: [asterisk-users] Pass through registration / proxy
The challenge is that calls to extensions on the Nortel have to ring the nortel phone AND the sip phone connected to Asterisk. -Original Message- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Daniel Tryba Sent: Wednesday, April 11, 2018 4:26 PM To: 'Asterisk Users Mailing List - Non-Commercial Discussion' Subject: Re: [asterisk-users] Pass through registration / proxy On Wed, Apr 11, 2018 at 12:04:18PM -0400, Telium Technical Support wrote: > Maybe proxy is the wrong word I chose.

(Still a beginner in training - but having fun > learning Asterisk) One of my first integrations was similar but with a Siemens. Easiest might be a SIP trunk (peer) between Asterisk/Nortel and have different prefixes for the Norted (1xx) and Asterisk (2xx) and route these to the other. The SIP endpoints simply register to Asterisk. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?
