[SIPForum-discussion] Reliable Provisionable Response to the Re-Invite.

[sreekant nair]

Hi Alex, 

If you mean " Can a Re-Invite generate a 18X response from the UAS?", here is what I found in RFC 3261[sec 14.1 pg 86]
Unlike an INVITE, which can fork, a re-INVITE will never fork, and
   therefore, only ever generate a single final response.  The reason a
   re-INVITE will never fork is that the Request-URI identifies the
   target as the UA instance it established the dialog with, rather than
   identifying an address-of-record for the user.Sec 14.2 pg 88
   A UAS MAY choose not to generate 180 (Ringing) responses for a re-
   INVITE because UACs do not typically render this information to the
   user.  For the same reason, UASs MAY choose not to use an Alert-Info
   header field or a body with Content-Disposition "alert" in responses
   to a re-INVITE.
Hope that answers your question or at least gives you a pointer in the direction you want to go\

Cheers
Sreekant

Hi 
All,

 

Can a 
reliable provisionable response be generated for the Re-invite

Thanks.
