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 enterprises 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.
Note:
•
The ELIN feature for E9-1-1 is a license-dependent feature and is available only if
it is included in the License Key installed on the device. For ordering the feature,
please contact your AudioCodes sales representative. For installing a new License
Key, see ''License Key'' on page 763.

The ELIN feature for E9-1-1 is applicable to the SBC application as well as the
Gateway application for digital PSTN interfaces.

15.7.1 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:
