Subject: [SIPForum-discussion] Transport Mechanism in SIP



Hi All,

I am working on SIP & wanted to know what mechanism is used for
transporting SIP Messages. Because, it uses TCP for REGISTER & 200OK.
It uses UDP for all other SIP Messages. I wanted to know....... What is
the Standard practice?? TCP or UDP for teansporting SIP Messages.

Regards,
Praveen
