[SIPForum-discussion] Processing request Request-URI and To URI

[Joby Joseph]

Hi Parasu,


I find two questions raised in your mail and answer to your first question

  1. Is Request-URI and To URI should be same ?
     Joby> They need not be same, To URI indicates the actual called party
and Request URI points the next hope and it can be over written by the sip
proxies.

Best Regards,
Joby Joseph
