[OpenSIPS-Users] [Opensips 1.9] B2BUA and CANCEL

[Mehdi BOUDOU]

Hello,

I'm testing the B2BModule with this sipp Scenario (A simple CANCEL Call).

This is the results of the execution script throught Opensips with a proxy
configuration file

everything is OK with this sipp scenario.


When i tried to execute  the same scenario with the B2BUA Module( the
topology hiding), the execution failed.

this is the sipp result

The Originating Cancel was'nt forwarding to the other side, and the
Opensips timeout   Cancelled the terminating side and sent a 408 to the
Originating side.

Is it a mistake of Configuration file or Must I do a specific treatment of
CANCEL ?

Thanks in advance,
