Status

• Design team has submitted new versions of its documents– Draft-rosenberg-sipping-app-interaction-framework-01– Draft-burger-sipping-kpml-02– Draft-jennings-sip-app-info-01

• There is really only one main open issue (the big one) – next slide

• We don’t believe the design team alone can resolve this last issue

• We believe the group needs to make a decision on whether to adopt this work

Changes from Previous Rev

• Framework– Removed client-remote UI

feature interaction sections

– Mention MESSAGE for one-shot and monitoring KPML usages

– Remove bit about using KPML along with client-remote VXML driven UI for purposes of zero-latency barge-in

• App-Info– No error reporting

mechanism– Motivate instance and class

names– Sips as authorization

mechanism– Will use callee-caps instead

of an Allow-Schemes

• KPML– Added digit suppression– MESSAGE for reporting

The open issue: KPML DTMF reporting

• INFO– Can’t work within call

dialog– But spec mandates its only

within a dialog

• NOTIFY w. Implicit subscription– Known issues

• Explicit subscription from application– GRUU problem– Authorization

• HTTP– Not returning a script in

proposed scope

• New method– What does this buy us?

• MESSAGE– Seems to work – Adam

raised some UI issues though if its misrouted

– Kind of ugly

• Design team reluctantly chose MESSAGE

Proposal

• Continue to hammer out the open issue on the list– Hopefully it will conclude

• Adopt the framework and KPML as sipping items– They need broader input now

PIDF Phone

What is it?

• A set of presence states that describe a “phone” as an application– Considered black phones, wireless, enterprise

• States are things like in/out of call, registered, call-waiting, etc.

• Presence is a simple issue, but the presence states are related to phones, and thus sipping expertise

• These are important in the “device” and “service” views that have been discussed in SIMPLE

• Looking for comments and inputs to this work
