[SR-Users] Kamailio consult CNAM server through SIP Subscribe.

[José Seabra]

Hi Olle and Daniel,
Thank you for your replies, After receive your msg I looked again to my
script and i found the problem.

I didn't configure the correct failure_route block and the failure route
configured didn't print any msg on the logs, so I thought that it wasn't
entering on failure route.

Sorry for my mistake.

Anyway, How should i handle the CANCEL sip msg to an INVITE that is
suspended? (still related with this implementation)


Thank you for your support.

Regards
