[Serdev] ser 0.9.0, CANCEL/t_on_failure broken

[Bogdan-Andrei IANCU]

Andres,

The problem is not in ser, but in Asterisk... As your net captures 
shows,  * does not generate  any INVITE final reply when receiving 
CANCEL. It should sent a "487 Request Terminated".
The lack of this final reply keeps the transaction open on ser; when FR 
timer hits, internally "408 Timeout" is generated (after 120 secs) and 
failure_route called.

So the problem is *.
