[asterisk-users] Diagnosing call problem

That change did not fix the problem. Below is another trace from a
failed call this morning. 172.16.0.71 is the client, 172.16.0.245 is
the Asterisk server. All the RTP packets after the SIP are from server
to client.
Any further ideas are appreciated. (If I don't get this fixed this
week, I won't get to go home on Friday!)
