[Freeswitch-users] calls ending with MEDIA_TIMEOUT

[Dan]

Hi guys, I have been running two freeswitch boxes (13754M) that answer calls from a cisco 5300 (both on the same network) and records them to disk with a small lua application. This has been working well for the past few months. I decided to upgrade one of them to trunk ( git-3fbd9e2 2010-06-11 11-08-51 -0500 ) and have run into a problem. Some calls will fail with a MEDIA_TIMEOUT after a few minutes, the time it takes to fail ranges from 4 minutes to 10 minutes, I don't have a full sip trace or pcap dump yet, I reverted back to the old freeswitch version (on the same hardware) and have not been able to reproduce it in a test environment yet ( I continue to try). Below are the relevant lines from the log files for one of the calls: 

2010-06-23 07:42:19.033466 [DEBUG] switch_channel.c:2257 (sofia/external/nobody at 192.168.21.4) Callstate Change ACTIVE -> HANGUP 
2010-06-23 07:42:19.033466 [NOTICE] mod_sofia.c:884 Hangup sofia/external/nobody at 192.168.21.4 [CS_EXECUTE] [MEDIA_TIMEOUT] 
2010-06-23 07:42:19.033466 [DEBUG] switch_channel.c:2273 Send signal sofia/external/nobody at 192.168.21.4 [KILL] 
2010-06-23 07:42:19.033466 [DEBUG] switch_core_session.c:1023 Send signal sofia/external/nobody at 192.168.21.4 [BREAK] 
2010-06-23 07:42:19.033466 [DEBUG] switch_core_codec.c:146 sofia/external/nobody at 192.168.21.4 Restore previous codec PCMU:0. 

My configuration is bone stock, so the rtp timeout value is at 300, but I have some calls that have lasted only 4 minutes. One other piece of information is that on one of the recordings that was hung up after 4 minutes and 17 seconds the recorded file was only 24 seconds long (it stopped recording after the first 24 seconds) , so I'm assuming freeswitch did not think there were any rtp packets to record. 

Any ideas on where to start debugging this? I have setup a new freeswitch box connected to the same 5300 to reproduce, but have not been able to generate the call volume ( there where around 30 calls being recorded) yet, but I'm working on it. 

Thanks!
