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

[Julien Chavanton]

I am wandering if UA1 when generating a CANCEL should have set the Request-URI to the Contact-Header in the provisional response ?
Like in an ACK and BYE ?
I can not find the information about this in the RFC  3261
