Seeing SIP Internal Errors

omarquez@ecmc.org · ‎06-07-2018

I am getting errors below on the gateway and some users are reporting a sporadic loud beep after placing the call. After they hear the beep, users usually hang up. I have asked a few to keep the call active and it disconnects after 4 or 6 minutes. Could these errors be related to the loud beep?

For the first two errors, the IOS is timing out waiting for the dialog to be established for first one and then for second one waiting to receive a 100 trying. The third one is a dial-peer match issue which is common. Someone dialling incorrectly etc.

You would need to collect SIP debugs and pcaps to isolate the issue further.
