This page contains instructions on how to add an Intercom/Paging extension to the system.
The Intercom/Paging extension allows users to call several or all available extensions at the same time. The called extensions will hear the caller's announcements no matter if they pick up the phone or not.
To set up an Intercom/Paging extension, first you need to define its general settings. Then you may customize it using specific options. You may do this at any time later on by clicking the Intercom/Paging Setup icon in the extension's management page.
To add/remove numbers or groups to/from the lists, right-click the same icon. The Choose extensions/groups window will be displayed in a popup, where you can select the extensions/groups that you want to add/remove.
This section allows you to set up basic Intercom/Paging extension related options.
You may choose between:
In order for intercom/paging 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/Paging 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.
The maximum duration of the intercom/paging 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.
|Caller permission for any extension in organization|
When enabled, this option allows any extension in the organization to call the Intercom/Paging extension.
|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.
In this area, you will be able to indicate which extensions are allowed to call the Intercom/Paging extension.
In this area, you will be able to indicate the extensions that can be called by the Intercom/Paging extension.
Please note that if you call the Intercom and your extension is among those assigned to it, the call to your own extension will no longer be placed. In short, all the other extensions assigned to Intercom will be called, except yours.
To call all the extensions assigned to an Intercom/Paging extension, dial the short number of the Intercom extension.
If the Intercom extension is 0001*003, you need to dial 003 (its short number). All extensions assigned to Intercom 003 will receive your call.
Suppose an Intercom is assigned several extensions. To call only a particular extension assigned to an Intercom/Paging extension, dial the short number of the Intercom, plus the short number of the extension you want to call in particular, followed by *.
If you want to call extension 0001*009 using Intercom 0001*003, you need to dial 003009*. Only extension 009 will receive your call.
To call a certain group of extensions that is assigned to a Intercom/Paging extension, dial the short number of the Intercom, plus the ID of the group of extensions, followed by *.
If the ID of the group of extensions is 12 and you want to call it using Intercom 0001*003, you need to dial 00312*. All the extensions in that group will receive your call.
