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 General section, configure basic settings for the emergency number.

    Setting Description
    Name Enter a name to help you identify the emergency number.
    Emergency Number Enter the emergency number.
    Emergency Outbound Caller ID Priority Select which outbound caller ID will be sent to the Public Safety Answering Point (PSAP) in priority when an emergency call is made.
    Emergency Number Extension Scope Specify the extensions that are allowed to make emergency calls using the number.
    • All Extensions: All extensions can make emergency calls using this number through all emergency trunks specified in Outbound Rules.
    • Specific Extensions: Only the specified extensions can make emergency calls using this number, and only through the corresponding emergency trunk specified in Outbound Rules.

      If you choose this option, you need to select extensions in the subsequent settings.

    Note: For Hot Desking phone: The virtual extension assigned to the phone is not restricted by the setting. However, when a user logs in to the phone as a guest, the user's own extension will be subject to the rule configured here.
  3. In the Outbound Rules section, configure trunks for emergency calls.

    Note: Emergency calls have the highest priority. If the selected trunk is in use, PBX will terminate the ongoing call, and place the emergency call.
    1. Click Add, then configure the following settings.
      Setting Description
      Trunk Select a trunk for emergency calls.
      Trunk's Emergency Outbound Caller ID Enter the Emergency Location Identification Number (ELIN) that you have purchased from the trunk provider.
      Strip Optional. To strip digits from the beginning of the emergency number, enter a value in this field to define how many digits will be removed.

      For example, if you set the field to 1, when a user dials 8911, the PBX will remove the first digit (8) from the emergency number and call out 911.
      Prepend for Emergency Number Optional. If the ITSP requires a prefix to place outbound calls, enter the provided prefix number in the 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.
      Extensions/Extension Groups Optional. If only specific extensions are allowed to use the number for emergency calls, select extensions authorized to use the emergency trunk.
    2. Optional: Repeat step a to add another trunk.
      Note: If the first trunk cannot work properly, the PBX will use the second trunk to make calls.
  4. Click Save and Apply.

What to do next

  • If Emergency Outbound Caller ID Priority is set to Extension's Emergency Outbound Caller ID, to provide the PSAP with the emergency caller's precise location, you may need to purchase multiple ELINs from ITSP and assign these ELINs to extensions or hot desking phones.
    Note:
    • For an extension without ELIN, the common ELIN for the trunk will be applied directly.
    • For a hot desking phone without ELIN, the system uses the ELIN assigned the logged-in extension first; if the extension does not have an ELIN configured, , the common ELIN for the trunk will be applied.
    • To assign an ELIN to an extension, complete the following settings.
      1. Log in to PBX web portal, go to Extension and Trunk > Extension, click to edit the desired extension.
      2. Under the User tab, scroll down the Outbound Caller ID (DOD) section, enter the ELIN in the Emergency Outbound Caller ID field.

      3. Click Save and Apply.
    • To assign an ELIN to a hot desking phone, complete the following settings.
      1. Log in to PBX web portal, go to Auto provisioning > Phones, click to edit the desired hot desking phone.
      2. In the Options section, enter the ELIN in the Hot Desking Emergency Outbound Caller ID field.

      3. Click Save.
      4. One the Phones page, click beside the hot desking phone and click OK in the pop-up window.

        The phone is reprovisioned and associated with the ELIN.
