Thanks Somesh,
Yes my stack will stamp TCP or UDP into the Via prior to transmitting the
message. I was really querying which fields in the message inform the stack
as to which socket type (i.e. stream, datagram) to send the message out on.
I wonder, does your answer imply that examples such as message F1, in
section 3.1 of RFC3665 are syntactically incorrect as here we have an INVITE
with "transport=tcp" in the Contact: but no such parameter in the
Request-URI?
thanks,
Matt

Hi Matthew,
You have to change the Via also. Something like this
..
Via:SIP/2.0/TCP 172.16.25.17:5060;branch=z9hG4bK-c7542
