E9-1-1 Support for Microsoft Skype for Business

The Enhanced 9-1-1 (E9-1-1) service is becoming the mandatory emergency service required in
many countries around the world. The E9-1-1 service, based on its predecessor 911, enables
emergency operators to pinpoint the location (granular location) of callers who dial the 9-1-1
emergency telephone number.
Today, most companies implement an IP-based infrastructure providing a VoIP network with fixed
and nomadic users, allowing connectivity anywhere with any device. This, together with an often
deployed multi-line telephone system (MLTS) poses a challenge for E9-1-1 due to the difficulty in
accurately locating the E9-1-1 caller.
This section describes the E9- 1- 1 solution provided by Microsoft Skype for Business and
AudioCodes' device's ELIN interworking capabilities, which provides the SIP Trunk or ISDN (or
CAMA) connectivity to the E9-1-1 emergency service provider. This section also describes the
configuration of the device for interoperating between the Skype for Business environment and the
E9-1-1 emergency provider.

About E9-1-1 Services

E9- 1- 1 is a national emergency service for many countries, enabling E9- 1- 1 operators to
automatically identify the geographical location and phone number of a 911 caller. In E9-1-1, the
911 caller is routed to the nearest E9-1-1 operator, termed public safety answering point (PSAP)
based on the location of the caller. Automatic identification of the caller's location and phone
number reduces the time spent on requesting this information from the 911 caller. Therefore, the
E9- 1- 1 service enables the PSAP to quickly dispatch the relevant emergency services (for
example, fire department or police) to the caller's location. Even if the call prematurely disconnects,
the operator has sufficient information to call back the 911 caller.
The figure below illustrates the routing of an E9-1-1 call to the PSAP:
