I figured this out. In case other people encounter the same issue. Here is the solution: INVITE message has to specify TCP protocol in its header for SER to use TCP protocol, otherwise, it will use udp protocol by default.

Hi,

I am trying to do some tests using TCP protocol with SER as a proxy. SER accepts SIP message through TCP correctly, but after SER accepts SIP messages, SER automatically picks up UDP for transmission. Is there a way to force SER to use TCP for forwarding message?

thanks, Joy
