  15. Signaling 1400-0100 • Call setup time (dialing of last digit to ring at the PSAP), under expected peak load shall be less than 2 seconds. If CAMA signaling is in the path, then an additional 7 seconds is permitted. • Done i3 Requirement

  16. Signaling 1500-0100 • Voice Activity Detection shall be disabled for emergency calls. • Done • SIPc uses RAT4 which can turn on/off the silence suppression. i3 Requirement

  17. Media 0100-0100 • PSAPs shall accept voice, video and text media streams on RTP transport • Done i3 Requirement

  18. Media 0200-0100 • PSAPs shall support existing TDD devices including direct detection and demodulation of tones as well as via tone detection and demodulation at an intermediate VoIP gateway • Done • Needs no additional works i3 Requirement

  19. Media 0300-0100 • PSAPs shall have facilities to detect and react to silent calls • Done i3 Requirement

  20. Media 0400-0100 • It shall be possible for PSAPs to supply ringback media to callers • Done • SIP sends a 180 ringing response i3 Requirement

  21. Media 0500-0100 • It shall be possible for PSAPs to accept additional media (e.g. images) from callers without tearing down the call. • Can be done i3 Requirement

  22. Media 0600-0100 • The i3 solution shall specify a minimal (e.g. DiffServe) QoS mechanism for use for media presented to or originated from the PSAP • Can be done i3 Requirement

  23. Media 0700-0100 • i3 elements which originate media shall have media loopback mechanisms. • Can be done i3 Requirement

  24. Location 0100-0100 • Calls using VoIP or subsequent methods are expected to supply location with the call • Done i3 Requirement

  25. Location 0200-0100 • PSAPS shall accept location as civic and/or geo specified • Done i3 Requirement

  26. Location 0300-0100 • The format for location shall be PIDF-LO • Done i3 Requirement

  27. Location 0400-0100 • All representations of location shall include the ability to carry altitude. This requirement does not imply altitude is always used or supplied • Done i3 Requirement

  28. Location 0500-0100 • Altitude shall be provided if available. • Done i3 Requirement

  29. Location 0600-0100 • The Preferred coordinate basis (i.e. WGS-84) • Done i3 Requirement

  30. Location 0700-0100 • Implications of multiple Location Objects • Undefined behavior • This is standardization issue. i3 Requirement

  31. Location 0800-0100 • No assumption shall be made that the entity presenting the call to the PSAP has any knowledge of, or control over the provider of location. The location provider may be independent of all other service providers handling the call • Done i3 Requirement

  47. 3rdParty 0100-0100 • 3rd party originated calls should be fully supported in the i3 solution • To all 3rd party requirements, there is no difference between a normal sos call and a call from 3rd party. i3 Requirement
