[Freeswitch-users] Incompelete calls in the log files

[Andy Ayers]

Hi,

 

I have been investigating a number of calls coming in to my switch that
don't appear to complete properly. These are incoming calls to a service
which records voicemail messgaes.

 

When I look in the logs to see what has happened to these calls the logging
information seems to simply come to an abrupt halt at a certain point in the
call. In other words there is no information about the call being hung up or
the session ended. They all seem to end at the same point in the call and
the last few lines in the log file are:

 

018afe16-e402-11e0-8e40-a5b8fd8e2a79 2011-09-21 04:30:14.848903 [DEBUG]

switch_core_io.c:403 Engaging Read Buffer at 320 bytes vs 40

 

It's also then in most cases followed by a new call coming in:

 

39cade04-e402-11e0-8e41-a5b8fd8e2a79 2011-09-21 04:31:43.177540 [NOTICE]

sofia.c:4153 Channel sofia/external/anonymous at localhost entering state

I'm guessing the session has simply crashed somehow and freeswitch has been
good enough to recover from it.

 

Anyone had a similar experience or can shed any light on what's actually
happening and how to prevent it?

 

I'm on version 1.06

 

Cheers

Andy
