Intercom Help

The Intercom service is used to call an extension by forcing it to go off-hook and opening two-way communication. The service is particularly used for announcements addressed to an extension. When the call comes in to the extension which has an Intercom service enabled, called extension will ring once and then will automatically go off-hook (the phone speaker automatically becomes activated) and the caller will be able to make his announcement.

Note: Intercom service requires called extension to use one of the following SIP or analog phones which are able to automatically go off-hook:

The Intercom drop-down list has three available selections:

  • Allow Activation on Request - this selection enables the Intercom service for calls that are made through a call routing rule of the PBX-Intercom call type. Please contact your system administrator to ensure a corresponding rule is available for your extension.
  • Activate Always - this selection unconditionally enables the Intercom service on the extension.
  • Disabled - this selection disables the Intercom service.

The Activation signal drop-down list has three available sections:

  • Ring Only If Requested - this selection allows you to play audible signal if the Play audible signal before Intercom activation checkbox is enabled in the call routing rule of the PBX-Intercom call type.
  • Ring On Activation- this selection allows you to play audible signal before Intercom activation whether the Play audible signal before Intercom activation checkbox in the call routing is enabled or not.
  • Silent Activation- this selection allows you to activate the Intercom service silently, without any audible signal whether the Play audible signal before Intercom activation checkbox in the call routing is enabled or not(see Call Routing Wizard)

Attention: Intercom will not work if the called extension is in call. If this service is enabled along with Many Extension Ringing, Call Hunting or Forwarding services, Intercom will not take effect and other high priority services will be primary.
