I'm running Asterisk 10.7.0 with three sip trunks to my call termination
provider. For the most part everything works great.
However, at apparently random times and usually about 20 mins or so into
the call, the outbound audio stream dies.
The call stays connected and the inbound audio works fine.
So I've been watching this problem and was finally able to get a pcap
while it happened.
I've attached a sanitized text version of the SIP signaling
surrounding the time the outbound RTP stream dropped on this
particular call. I'm no SIP expert, so there may not be enough info in
the file to tell anything. A few notes about the file:
1. X.X.X.X is the public IP our asterisk server is behind.
2. Y.Y.Y.Y is the IP given to us by our provider to use in our SIP
trunk through which inbound calls arrive.
3. Z.Z.Z.Z is the IP of our provider's server involved in the RTP stream.
4. DID is our DID.
5. CID is the number of the incoming caller.
6. The outbound RTP stream appears to drop three packets prior to the
SIP BYE request.
Any thoughts on what might be going wrong? Do I need to post more
info? Or am I on the wrong track altogether?
Kind Regards,
Chris
