I need to be able to create a trunk that uses TCP instead of UDP for SIP traffic to an Avaya CM based PBX.

I’ve done this several times with Yeastar appliances but can’t figure out how to get the trunk to use TCP instead of UDP on the Xorcom side.

Have tried using tcpenable yes in the parameters fields of the Advanced trunk screen. When I try to make a call using the route and trunk for the Avaya, I get the message: “outbound connection failed” after about 30 seconds.

I was able to get it to work using the following in the Advanced tab under Trunks:
peer tcpenable yes
peer transport tcp
peer tcpbindaddr 0.0.0.0

Don;t know if they are all necessary but it’s working now.
