I have a SIP trunk to CUCM 9 server 192.168.0.10 from CUCM 12.5(SU4) server 172.16.10.243 through a tunnel (Media Termination Point Required cheсked). Ping goes in both directions, telnet to port 5060 are open. The WWW control pages CUCM's are available, the call manager service is running and the SIP profile is in TCP mode. Everything seems to work but!
SIP trunk status down and Status reason local = 0
What could be? what's the status??
