Setting the Intercom/paging Extension
This page contains information on how to add and configure an Intercom Paging Extension.
Overview
The Intercom Paging extension type allows the user to call several or all the available extensions at the same time. The called extensions will be able to hear the caller's announcements whether they pick up the phone or not. You can customize the Intercom Paging extension by setting up the options detailed in the section below. If you do not want to finalize the process right away, you may skip this step and come to it any time later by clicking the Intercom setup icon available in the extension's management page. In order to add numbers or groups to the lists, you have to click the Arrow button. The Choose extensions window will be displayed in a popup, allowing you to select the extensions that you want to add.
Basic Settings
This section allows to set up the basic options for the Intercom Paging extension.
| Option | Details |
|---|---|
| Type | You may choose between:
|
| Alert-Info header Call-Info header | In order for intercom to work, the Alert-Info and the Call-Info headers must be sent from the VoipNow to the user's phone terminal. If the phone terminal supports Intercom and if it is able to read those headers, then it will automatically answer and you will not be required to fill in anything in these two fields. Newer firmware versions for certain devices such as Linksys, Polycom, Aastra, Grandstream or Snom (not necessarily for all of them) might require another value for the Alert-Info and the Call-Info headers, different from the default ones. In these conditions, you will be required to check with the phone manufacturer the values that must be filled in to enable automatic answering. ⚠️ This does not work when multiple phones of different types are dialed in Intercom. |
| Timeout | The maximum duration of the intercom session. At the end of this interval, the call is disconnected. |
| Play sound on connection | Each time the user is connected to the called extensions a sound is played. Use the  icon to view the available sound files or manually fill in the file location. A pop-up window listing all the sounds matching the name specified in the text will be displayed.
|
| Permission to call intercom for any extension in organization | When enabled, this option allows any extension in the organization to call the Intercom/Paging extension. If this option is disabled, you have to manually assign individual permissions in the Permission to Call Intercom For area described below. |
| Allow intercom to call all its assigned extensions simultaneously | When enabled, this option allows the Intercom to call all of its assigned extensions at the same time. Extensions from configured groups (i.e. groups of extensions assigned to an Intercom extension) however will not be called. |
