One could honor the expiration value instead of tearing down the session at half the expiration value. However rfc3261 section 12.2.1 mentions that the 408 SHOULD trigger a termination of the dialog. To avoid debating the 408 issue again and to avoid a SHOULD conflict, maybe the timer draft to reflect the rfc3261 SHOULD text. _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
