Hi,

This is a query regarding selection of transport while sending a
SIP request. If the target uri is of the form

sip:[email protected]:5061  what transport should be used ?

Should it be udp as per rfc 3263, section 4.1 which says:-

"Otherwise,if no transport protocol is specified, but the TARGET is a
numeric IP address, the client SHOULD use UDP for a SIP URI, and TCP for a
SIPS URI."
Or should it be tls since port 5061 which is default for tls is present in
uri.


Regards,
Gauri
