911 from hotels is an issue that was raised last year to the FCC after the tragic incident in Marshall Texas.
The FCC Ex Parte I filed from my meeting last year with Commissioner Ajit Pai is here:
When dealing with E911 in any environment, especially hotels remember the 3 primary concerns / best practices:
1.) Direct Access to 911 with and without an access code (PBX Based Feature)
2.) On-Site Notification that an emergency call has occurred (PBX Based Feature)
3.) No interception of calls locally by untrained staff (Policy and Configuration)
Remember that the mechanism that 911 uses to report information to the PSAP is caller ID and the associated ALI record. Because of this, unless a unique DID number is assigned to each and every hotel room, there is no way of communicating the room number to the PSAP. This is why On Site notification is critical, and why you really don't need anything more than a single number to report to the PSAP on 911 calls. public Safety needs to get to the right building, and when they get there, they need to be met by people that are aware of the emergent event, and can get them access.
Focusing on the
local reporting and notification, and not the PS-ALI databases gets the job done, and is the most efficient way to do it.
From a 3rd party perspective, there are various ways of notifying that a 911 call has been made. In an IP Office 9.X system, the recommended mechanism is SNMP Traps that occur as soon as a digit string marked properly is detected. CDR events happen AFTER THE CALL is completed and are not recommended for 911 notification. TAPI events, depending on configuration and scale, have not been tested under load to ensure 911 TAPI events are not delayed, so use caution there.
