Emergency Numbers

Introduction

When an emergency number is dialed, the PBX prioritizes this number and ignores any outbound, in-office or out-of-office rules.

Configuring an Emergency Number

To configure emergency numbers, go to Admin > System > Emergency.

  • Click on Add and specify:
  • Rule Name i.e. Police, Fire etc.
  • Number the emergency number to be dialed.
  • Now decide whether this emergency number will be system wide or limited to a department or number of extensions
  • System Wide - Do nothing
  • If limited to extension or department, specify accordingly in the “Calls from departments” option.
  • Now configure on which SIP trunk the number should be dialed. Set at least one mandatory first route and up to 4 alternative routes for calls to the emergency number.
  • In Outbound Caller ID you can optionally set a custom entry to override the default caller ID.
  • Click on Save
  • In the USA you can take advantage of E911 Geolocation, when using a VoIP provider that supports it. You can find the details here.

Notifications

In the ‘Notifications’ tab, configure notification options when an emergency number is called:

  • “Send email to one or more email addresses separated by commas” - enable and specify one or more email addresses; do not use spaces.
  • “Send chat notification to” - enable and select to notify the caller's Department Managers, all the caller's Department's members, or Managers across all Departments via chat message.
  • “Play announcement (Extension/Ring Group)” - call an extension or ring group and playback the selected audio announcement.
  • Click OK to save the notification options.
  • You can customize the email notification text in Admin > Advanced > Templates > Email Templates, then choose "Emergency call" from the dropdown.
