    How does that accomplish telling the PSAP what room or floor the person is on?


    You are right, it wont deliver address. It will route to correct PSAP and deliver subscriber name only. That is I guess more for mobile devices.

    There is another option: 


    Bandwidth provides a service where your subscribers can call 911 without using phone numbers. Instead of the typical ANI, you register a SIP URI username for the subscriber, along with their name and location, in our databases. When that caller needs help, you send the call to us with the SIP URI instead of the ANI in one of the caller-identifying SIP headers (See section "Supported Privacy Types). Upon receipt of the SIP INVITE from that SIP URI, Bandwidth will send the registered address for that caller to the PSAP. In addition, since most PSAPs are unable to make direct connections to SIP proxies, Bandwidth will temporarily reserve a number from our own PSTN pool to support PSAP callback. If the PSAP needs to call your subscriber back, Bandwidth will bridge the call from the PSAP to your subscriber's SIP UA.

    Those are just options and I'm thinking out loud. You could register username with room number. 


  2. Hi,

    You can try with Bandwidth. They support sip header: X-Geolocation:<geo: 39.752913, -104.996080;timestamp=20161213164900> that will route call to correct PSAP based on geolocation. If kazoo supports custom headers maybe that can be added to specific device and then transmitted with 911 call.

    From documentation:


    The caller will be routed to the PSAP matching the lat-lng in the geolocation header. If the latlng is invalid or the timestamp older than 60 minutes, the call will go to the emergency call center.
