[OpenSIPS-Users] *** correction *** Opensips is responding(SIP/2.0 503 No destinationavailable) to a CANCEL request.

[Bogdan-Andrei Iancu]

Hi Julien,

first of all ,you should not do dispatching for CANCEL - it should be 
automatically routed by TM in order to go where the INVITE was sent (at 
transaction level). You do not need to manually route the CANCEL.

Regards,
Bogdan
