Normally you would want to set it to auto if you were connecting to a trunk or sip provider that specifies their protocol via DNS SRV. With most gateways you would want to use UDP as a preferred way to connect. Some gateways and providers don't like large header messages over udp so you might switch to tcp. > The reason I ask is the Avaya Session Manager that we're connecting to > sends two Via options: SIP/2.0/UDP and SIP/2.0/TCP.
