Set up Enhanced Emergency Calling

To ensure that users can make emergency calls for help when an accident occurs, you need to set up emergency calling in Yeastar P-Series PBX System. This topic describes how to set up enhanced emergency calling in Yeastar P-Series PBX System.

Prerequisites

Purchase enhanced emergency service from an Internet Telephony Service Provider (ITSP).

ITSP will provide DID numbers that are associated with your locations. DID number is also called Emergency Location Identification Number (ELIN).

Procedure

  1. Log in to PBX web portal, go to Call Control > Emergency Number, click Add.
  2. In the Name field, specify a name to help you identify it.
  3. In the Emergency Number field, enter the emergency number.
  4. In the Emergency Outbound Caller ID Priority field, select which outbound caller ID will be sent to the Public Safety Answering Point (PSAP) in priority when an emergency call is made.
    • Trunk's Emergency Outbound Caller ID: Select this option if you want to set a common ELIN for all extension users. PSAP receives the trunk's emergency outbound caller ID no matter who makes the emergency call, which indicates PSAP receives a common location information.
    • Extension's Emergency Outbound Caller ID: Select this option if you want to assign ELINs for individual users.
      • Extension users with specific ELINs are associated with their respective locations.
      • Extension users without specific ELINs share a common ELIN (the trunk's emergency outbound caller ID) and are associated with a common location.
  5. Under the Outbound Rules tab, configure trunks for emergency calls.
    Note: Emergency calls have the highest priority. If the selected trunk is occupied, PBX will terminate the ongoing call, and place the emergency call.
    1. Click Add.
    2. In the drop-down list of Trunk, select a trunk.
    3. In the Trunk's Emergency Outbound Caller ID field, enter the Emergency Location Identification Number (ELIN) that you have purchased from the trunk provider.
    4. If the ITSP requires a prefix to place outbound calls, enter the provided prefix number in the Prepend for Emergency Number field.

      The prefix will be automatically added at the beginning of the dialed emergency number. For example, if you set the field to 1234, when a user dials 911, the PBX system will add 1234 to the emergency number and call out 1234911.

      Important: Carefully configure the prefix according to the ITSP's requirements, or the emergency calls may fail.
    5. Optional: Repeat step a - step d to add another trunk.
      Note: If the first trunk cannot work properly, the PBX will use the second trunk to make calls.
  6. Click Save and Apply.

Assign ELINs for individual users

To provide the PSAP with the emergency caller's precise location, you may need to purchase multiple ELINs and assign these ELINs to extension users.

  1. Log in to PBX web portal, go to Extension and Trunk > Extension, click to edit the desired extension.
  2. On the extension User page, scroll down the page, enter the ELIN in the Emergency Outbound Caller ID field.
  3. Click Save and Apply.

After the user dials an emergency number, the PSAP will locate the specific geographic location of the user by the extension user's ELIN.
