 1) I guess for 491 Request Pending, the User Agent which received response 491 for the ReInvite must retransmit a ReInvite again after a particular time period. you can look into the RFC specification for ReINVITE or even UPDATE method.2) I think  it is not easy to identify that a ReINVITE is for session modification or whatever its purpose without parsing the SDP.Regards,Ayyanar Original message From:Ashoke Kumar Ghosh< ashoke.k.ghosh at gmail.com >Date: 07 Dec 08 12:15:09Subject:[SIPForumdiscussion] Queries regarding B2BUA & reINVITETo:Hi All, I have the following queries. 1.
