Subject: [SIPForum-discussion] Query for method name in Request URI

Hi,
I have a query for method available in Request URI.
According to rfc 3261 section 19.1.5

"If the URI contains a method parameter, its value MUST be used as the method of the request."

Now suppose the UAC receives 302 Moved Temporary with Contact like

sip:biloxi.com<http://biloxi.com>;method=REGISTER;transport=tcp?to=sip:bob%40biloxi.com<http://40biloxi.com>

Doest that mean the UAC need to send REGISTER request to sip:biloxi.com<http://biloxi.com> ?

If not then what is the meaning of this method name in the Request URI?

Thanks in advance
