[Freeswitch-users] Transporting SIP over TCP

[Tzury Bar Yochay]

> It just works... to force TCP you append ;transport=tcp
Hi Brian

In fact this is exactly what I did and I could not get it work.
I am using a console based application supplied by pjsip.org and when
trying to register i get some error messages saying 'invalid transport
"SIP/2.0/tcp"' and 'REGISTER (30669) has invalid Via'

using the very same client against iptel.org seems to work.

> In reality you should be using SRV records.
can you please elaborate a bit more about this?


I am dumping below the cli output.
thanks in advance for your time and attention
