[Spce-user] mr5.1.1 dropping calls

[Henk]

Hi Andrew,

Unfortunately the system is back to 5.01 now, which was more stable. I 
have the original full proxy log available, I will send this in private.
I did some capturing and found that the transaction matching fails when 
a re-invite is send (exact copy of original) after one minute due to an 
expiring 120 second SIP-timer (on the trunk-side).
If you need more information please let me know. I still have a test 
system with the same configuration, but it will take a lot of time to 
reproduce this.

Regards,

Henk
