Why not transport descriptions carry the key info than using media band, jingle also is offer answer model.

There is a lot of ongoing discussion about this topic on the rtpsec mailing list at the IETF (mostly ZRTP vs. DTLS-SRTP). What we need to do is enable the two parties to include the right bits in their signalling exchange so they can use DTLS-SRTP if they want to (ZRTP is negotiated entirely within the media band, so it is totally out of scope for Jingle). And I think we have already defined those bits in XEP-0167 and XEP-0180, because the Jingle client can include "UDP/TLS/RTP/AVP" as the value of the <content/> element's 'profile' attribute -- this essentially a Jingle mapping of what is specified in draft-fischl-mmusic-sdp-dtls. Naturally the XMPP signalling path should also be secure, but that is a separate problem (join the [EMAIL PROTECTED] list to discuss it if you'd like).
