  1. sos Henning Schulzrinne Columbia University 53rd IETF - SIPPING

  2. Summary • Address convention: • sip:sos@local-domain if known • sip:sos@aor-domain if not known • also: sos.service (e.g., sos.police, sos.fire, sos.rescue) for specific services • Should UA translate 911 and 112 to sos? • First proxy that recognizes sos routes to appropriate emergency call center • maybe just use sos@aor-domain always 53rd IETF - SIPPING

  3. Summary of discussion • Out of scope: service behavior • no caller-initiated disconnect  even PSTN can’t do this • call back • Out of scope: finding appropriate emergency call center • likely to be country-specific • currently, proprietary protocols (e.g., Intrado) • but use of universal identifier simplifies UA design: • accidental disconnect prevention • inclusion of location information 53rd IETF - SIPPING

  4. Going forward • Status: WG item? I? BCP? PS? • Unlike service URIs, agreement very helpful • prevent accidental assignment to non-emergency use (e.g., ad-hoc conference) • UA behavior • Informal coordination with NENA transition WG • Consider it ready for WGLC (except for IANA consideration section) 53rd IETF - SIPPING
