This phone system has ~50 users/phones
It has been running smoothly for over a year now with BroadVoice SIP Trunk service, but the last few days has been dropping both internal and external calls randomly…
I have 2 examples of call drops that I can find in the logs
In Example 1:
Internal_UserA calls Internal_B
A and B talk for 4 seconds (2way audio)
A is talking and gets garbled, then disconnected
B is still on the line, asks if A is there, then hangs up
In example 2:
Internal_UserC calls Outside line.
C goes thru IVR prompts for 40 seconds
Outside Line IVR gets garbled and disconnects.
C hangs up
Possibly related: I updated all the modules in the phone system a few weeks ago.
I tried rebooting the system today, but still having issues.
I agree with dicko. Check to see if you have an unusual amount of traffic on the network. If internal calls are experiencing the same issues, I would look for an infected system, or someone using bittorrent or similar on the network. Try speedtest.net or something similar from a few machines and see if your ping time and bandwidth are sufficient. Even ping machine to machine internally. If your network infrastructure is decent, you should get 2-3ms ping times internally. Ping your phone server and see if it responds any differently than another workstation. Good luck!
Heres some more debug info — it looks like a bunch of extensions are losing connectivity including the SIP Trunk to BroadVoice
Maybe the PBX is having its own network issues on its card or server port?

Can you run a ping from the phone server to one of your phones and just leave it running? That might tell you if it’s something specific to SIP if the pings are fine while SIP is not responding…
