As Jonathan as said some time back, "Transporting DTMF in INFO is not an IETF approved approach for conveying DTMF. It is a bad thing, in fact, for many reasons, not the least of which is the fact that DTMF will get sent in the signaling path even when no one cares, increasing proxy load uneccesarily."
These are the docs I am telling, I am not sure if we have newer version of the drafts, http://www.ietf.org/internet-drafts/draft-rosenberg-sipping-app-interaction-framework-00.txt http://www.ietf.org/internet-drafts/draft-jennings-sip-app-info-00.txt http://www.ietf.org/internet-drafts/draft-burger-sipping-kpml-00.txt -Sreeram Covansys Bangalore-INDIA -----Original Message----- From: Gupta Adetya-A19368 [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 13, 2003 9:04 AM To: KANUMURI Sreeram; Jade Chen Yan; Sip-Implementors (E-mail) Subject: RE: [Sip-implementors] DTMF in SIP Sreeram, Why INFO method should not be used for DTMF ?

We want to use INFO to carry the DTMF message, but I am not sure if the RFC 2976 is obsolete since RFC 2543 is replaced by RFC 3261? or can anyone give me other solutions on this problem.
