[asterisk-dev] Call drop and strange CDR records

Hi,

I have some (5-10 per day on an average 250 calls/day) incoming calls 
dropped after 25 to 60 seconds.
Asterisk is 1.2.10 + BriStuff 0.3.0-PRE1s on one hand (with 4 ISDN lines...)
Snom 320 SIP IP Phone (release 6.2.3) on the other.

With SIP Debug on, it *_looks_* like a normal call clearing, but the 
users are complaining, stating that no one on either end had hanged up.

Doing a "sip debug" on asterisk shows a normal call clear from the snom 
(Receiving a SIP BYE frame).

But, the CDR record looks strange (and this is the only common point 
between those calls): Both the session timer and the talk timer are the 
same, but according to the log, the call are all answered after 3 to 5 
seconds ringing (so those timers should show this difference).

Thanks,
Fabrice Cahen
