[SIPForum-discussion] Logical Recipient of REGISTER and INVITE

[Sandeep Mohapatra]

Hi,

If the very next proxy of the UA is doing both the jobs

1. Forwarding the requests based on DNS and address resolution
2. Registar server

In this case the RURI of REGISTER and INVITE request will be the same. Else if they are  different servers then the UA generates the requests(REGISTER and INVITE) will have two different  addresses in their RURIs

Hope this clarify . Please let me know in case of additional queries.

Regards,
Sandeep

Okay, in that case, I would like to re-phrase/simplify my 
question as follows:
 
For a User Agent using SIP-URI formats, is 
the "logical recipient" in the Request-URI always the same for REGISTER and 
INVITE methods?
 
Best Regards,
Jerry

        Hi Jerry,
         
        The domain name of RURI and To Header is not 
        necessarily to be the same. To : header 
        contains the end destinations address. RURI contains the immidiate 
        destination's(UAS) address. 
         
        If both the proxy and the UAS reside in the same domain then the 
        SIP URI domain of To and RURI will be the same. Let me know in case you 
        need more clarifications.
         
         
        Regards,
        Sandeep

Hello,

When using SIP-URI formats, is the "logical recipient" in the
Request-URI
and To-Header URI, always the same for REGISTER, and INVITE methods?

By logical recipient, I mean, the domain portion of the following:
"sip:AoR at domain".

Best Regards,
Jerry
