[asterisk-dev] [Fwd: [Asterisk-Users] Provisional problem with SIP channel]

Hi,

I'm using the Perl AGI interface for a prepaid card platform. And 
sometimes (almost twice an hour), asterisk doesn't detect a call has 
been hung up. The call is so hung up when the time limit for the call is 
reached (the corresponding prepaid card is then emptied ...).

I've tried to look in the asterisk log files to find anything suspect 
with these calls, and I've found a debug message which looks to be my 
problem :
chan_sip.c: (Provisional) Stopping retransmission (but retaining packet)
Each time I've got that, the call is not normally hung up.

Hopefully that's not a bug in asterisk !

Is there anyone who could help me ?

It's hard to extract logs as it's hard to identify these few calls 
(that's not a constant problem). Here are some logs I've extracted :
