[Freeswitch-users] MEDIA_TIMEOUT after long duration call

Tue Apr 13 10:03:55 PDT 2010

I am running the last stable release 1.0.4 and could reproduce the failure. Sometimes it happens in a call of 4 minutes duration.

I don't have a rtp packet trace but there is one more reason for MEDIA_TIMEOUT. I had a look at the sourcecode and followed the calls down to the winsock function recvfrom. It also could be a socket error.  If the recvfrom function returns -2 a MEDIA_TIMEOUT will happen. Maybe something was wrong with the network hardware cables, switch ..
I changed my hardware. Test is running...

How can I enable a rtp packet trace? It think I should check this too.
