Other drafts of interest • As usual, WG documents receive priority for agenda slots • Other documents get agenda time based on level of mailing list discussion and issues requiring discussion • All agenda requests, with links to docs, are logged at: http://www.softarmor.com/sipping/meets/ietf70/Agenda_request.html • Single slide per topic always welcome for documents not receiving agenda time.

  19. Basic KPML • Arguments against KPML • Too hard for itty-bitty big gateway to dynamically generate XML • Too hard for itty-bitty big gateway to parse and run digit map recognition engine • Too hard for tiny applications to create KPML request document • Basic KPML • Profile of KPML that auto-subscribes <regex>.</regex> pattern • Fully forward-compatible with KPML • Does anyone care, or are arguments bogus?

  20. Text conversation turntaking limitationsdraft-hellstrom-text-turntaking-00.txt Need for gateways SIP devices <> PSTN textphones. For indication to SIP device user what turn-taking habits must be applied. For routing to the most capable device for text conversation. Defines a Media feature tag sip.text-turntaking to be declared by gateways Proposed values: no, unspecified, soft, strict Values match different PSTN textphone types behind a PSTN/SIP gateway. Needed to avoid confusion for SIP text users who are used to full simultaneity of text and voice. Same function was discussed as an SDP media-contents attribute in mmusic, but cancelled. Is using the SIP Media feature tag right way to go? Is there interest in this work in the SIPPING WG? V.18 ToIP ToIP-PSTN GW PSTN Textphone ToIP able SIP Phone

  21. Real time text gateway BCPdraft-hellstrom-txtgwy-00 SIP devices with real-time text capability may interoperate with textphones through gateways This BCP describes Routing through text capable gateways Indicating text capabilities Media handling between limited functionality PSTN textphones and full functionality SIP devices Starting text usage mid-call and alternating text-voice SDP examples Builds on requirements from draft-ietf-sipping-toip Is there interest in this work in the SIPPING WG?
