SIP-T talks about mapping between different session setup protocols. It's very different from requirements in MediaCtrl.
Please don't mix them together just because INFO is used. 8-) Peili -----Original Message----- From: Chris Boulton [mailto:[EMAIL PROTECTED] Sent: Thursday, September 06, 2007 4:59 PM To: Peili Xu; Henry Sinnreich Cc: sip Subject: RE: [Sip] INFO - more on SIP-T I don't think the control channel concept for SIP is proper to replace SIP-T, because we need SIP to do SDP exchange and most of the ISUP information is semantically related to SIP dialog setup messages. [Chris Boulton] Sorry - this doesn't fly for me. The Control channel being developed in MediaCtrl has a strong requirement to explicitly 'relate' its primitives and commands to a SIP dialog (as it needs to work for IVR commands to a SIP dialog).
