My ITSP ask me to register CME to his SIP trunk not by usial UDP 5060 port but using TCP 5060.
How to do it?
CME version 12.0 on 2911 router IOS 15.7(3)M5

Hi Alex,
You have to use the below in the config to register using TCP:
sip-ua
registrar XXXX expires XXX tcp auth-realm XXXX
no transport udp
Also in all the dial-peers pointing to the SIP trunk, you can use the below command:
dial-peer voice X voip
session transport tcp
