[SIPForum-discussion] Transport Mechanism in SIP

Thu May 10 07:03:14 UTC 2007

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
