[reSIProcate-users] resiprocate access violation crash when getting invite

[Pornvit Saksobhavivat <tondynamic@xxxxxxxxx>]

Hi,

My company use resiprocate library for communicating with Microsoft LCS server.   It crashes often like once to twice a day on each server.  The stack trace point to when it receive an invite and try to Notify back.  It crashed with access violation exception. Could someone give me a clue what wrong with it?  The stack trace looked like:

We use resiprocate 1.6 and it was modified to fit sip messages from LCS.   We also patch some file from 1.7 release in the library too. 

Thank you,
