[Jingle] XEP-0181: Jingle DTMF

[Johansson Olle E]

I agree that in most situtations, DTMF in the media stream is to be  
preferred, mostly because
of timing issues. In some cases, DTMF is handled out of band for IVR  
situations, then maybe
KPML could be used in the XMPP stream. It's an XML-based definition in  
RFC 4730.

Please also note that 4733 REQUIRES use of SRTP, where RFC 2833 doesn't.
That's propably why most SIP devices still only claim support of 4733.
