[OpenSIPS-Users] B2B routing

[Anton Zagorskiy]

Anca,

one more question :)


Is it possible to make a timer that will represent a lifetime of finished
B2B dialog to catch such SIP requests? (SIP requests for already finished
session).
I just want to say that I'm not interested in such errors (does anyone?) and
I'm afraid of missing 'real' errors.

Also, it will be very helpful, if B2B says that it received request for
already finished session.
