15.8.4 Configuring AudioCodes ELIN Device

This section describes E9-1-1 configuration of the AudioCodes ELIN Gateway deployed in
the Skype for Business environment.

15.8.4.1 Enabling the E9-1-1 Feature

By default, the ELIN device feature for E9-1-1 emergency call handling in a Skype for
Business environment is disabled.

To enable ELIN feature:

For the IP Group through which you want to communicate with the public-safety
answering point (PSAP), configure the 'SBC PSAP Mode' parameter to Enable. For
more information, see Configuring IP Groups on page 326.

15.8.4.2 Configuring the E9-1-1 Callback Timeout

The PSAP can use the ELIN to call back the E9-1-1 caller within a user-defined time
interval (in minutes) from when the initial call established with the PSAP has been
terminated. By default, an ELIN can be used for PSAP callback within 30 minutes after the
call is terminated. You can change this to any value between 0 and 60:

To configure the E9-1-1 callback timeout
1. Open the Priority & Emergency page (Setup menu > Signaling & Media tab > SIP
Definitions folder > Priority and Emergency).
2. In the 'E911 Callback Timeout' field (E911CallbackTimeout), enter the required
callback timeout.
3. Click Apply.

15.8.4.3 Configuring SBC IP-to-IP Routing Rule for E9-1-1

To route incoming E9-1-1 calls to the emergency service provider's PSAP server, you need
to configure routing rules in the IP-to-IP Routing table for routing between the emergency
callers' IP Group and the PSAP server's IP Group. The only special configuration is to
define the emergency number (e.g., 911) in the 'Destination Username Prefix' parameter of
the IP Group belonging to the E9-1-1 callers. The following example shows IP-to-IP routing
rules for E9-1-1 in a Skype for Business environment:
