Because old style PSTN will not support it ever? And for those who is  
vital to interop with them, this is not an option?

For PSTN integration I really don't see any other option except RTP- 
based one. At least in our environment, a telco.

About other protocols: I think that it's great to have standards for  
signaling other protocols. I just don't see the need to be inside the  
jingle spec.

If my Jingle buddy, via a gateway, has a JID X, I can disco JID X,  
find out support for "Electric Chair Protocol", and use the  
appropriate JEP to signal my pain to him. Why do I need to put this  
inside Jingle?

Same goes for DTMF even: I disco my jingle buddy, the gateway  
responds with "DTMF-over-XMPP" protocol, and you follow that JEP,  
probably with a <message> of some sort.

Really, XMPP already does this. I'm probably missing something, but  
why do we want to put this inside Jingle?
