SIP over UDP and TCP

Posted:Thu 19 of Jan, 2017 (16:10 UTC)

I have Asterisk 11.14.1. I have a mix of Cisco phones on the system. Using a mix of SCCP, SIP TCP, and SIP UDP. I also have a SIP trunk using UDP.

The SCCP phones work fine and I have enabled SIP TCP and those phones work fine as well. The issue I'm having is with the Cisco 7961s. Even though in the config file, I specified to use UDP, when they connect, I get an error in the Asterisk log that status they only support UDP and cannot connect on TCP.

Any ideas how I can get them working without breaking anything else.
