[Sipping] work in progress from the app interaction design team

[Jonathan Rosenberg <[e-mail]>]

Folks,

The app interaction design team has been working quite diligently to 
progress its work, resolving issues like DTMF and stimulus signaling 
within SIP systems. Several drafts were released this round addressing 
this issue. Some have appeared in the I-D archive already, others are 
coming. They are:

http://www.jdrosen.net/papers/draft-rosenberg-sipping-app-interaction-framework-00.txt
http://www.ietf.org/internet-drafts/draft-burger-sipping-kpml-00.txt
http://www.ietf.org/internet-drafts/draft-jennings-sip-app-info-00.txt

and an update to the requirements draft that Bert Culpepper and Robert 
Fairlie-Cuninghame have been working on.

THe first of these drafts provides the basic framework for how stimulus 
interaction works with applications, and it discusses the role of markup 
languages and media streams in that context. The second draft proposes a 
new markup language that allows network applications to collect 
traditional 12-digit keypad input from clients. The last of these 
proposes a SIP extension that can meet the requirements described in the 
framework document.

THis is definitely work-in-progress. There are still many open issues, 
not the least of which is the now-infamous HTTP vs. SIP for conveying 
keypad input to applications. But, there has been much progress generally.

Comments and questions welcome.
