So can we please stop with the 'call-block on all incoming deaf > callers' bit? GV: I agree - this is not a block on any communication with users who are deaf -- but just a less timely, less flowing, and somewhat slower means of communication. IM is also the mode that some deaf people prefer- while others prefer RTT. but please also don't call messaging 'real time' because it isn't. It is "instant delivery of a message" but it is messaging - not real time conversation. > > That is, the spec should generally have requirements for what the spec is, an > extension to XMPP IM, as opposed to being a part of a 'total conversation' > system that includes A/V, RTT, and possibly other extensions.

GV: agree that this is a technical spec for RTT in XMPP IM. That XMPP-RTT can be combined with voice and video is OK to note in passing -- as well as the fact that this is of advantage to some users. But unless the technical details for how this would or should or must be done (for interoperability) in conjunction with XEP-0301(for interoperability), then it is a note in passing and not part of the spec. It would be handled separately. But the spec should not omit things necessary to allow this interworking -- or allow things that would block it -- or block the effective use of RTT in these ways or in emergency situations.
