Matrix PRASAR UCS - Intercom

Matrix PRASAR UCS System Manual 925
Intercom
What is this?
The Intercom feature of PRASAR UCS enables extension users to connect quickly with any desired extension,
without waiting for the called extension to answer.
• PRASAR UCS will serve an Intercom call made by an extension only if:
• the called extension is in idle state.
• the called extension is able to identify the incoming call as an intercom call (applicable in the case of
Standard SIP Phones).
• the calling extension has Intercom in its Class of Service.
• the Priority of the calling extension is higher than that of the called extension.
• PRASAR UCS supports Intercom using Call-INFO / Alert-INFO Message. For a list of IP phones on
which this feature has been tested, see “PRASAR UCS Features tested on IP Phones of different
Brands” in the Appendix.
How it works
• A’s extension number is 3001 with Priority Level ‘7’ and ‘Intercom’ feature enabled in the Class of Service.
• B’s extension number is 3003 with Priority Level ‘5’.
• A wants to quickly connect to B. A dials the Intercom feature code *5 followed by B’s number, 3003.
• PRASAR UCS places the Intercom call on B.
• B’s extension is idle at the time of the call, and the speaker of B’s phone goes OFF-Hook, creating a
speech path between A and B.
• A can now talk with B.
Feature Interactions
• Do Not Disturb (DND): If the called extension has set DND, PRASAR UCS will not place the intercom call
on the called extension.
• Privacy from DND Override: If DND as well as Privacy from DND Override is enabled in the Class of
Service of the called extension, PRASAR UCS will reject the Intercom call.
• Call Forward-Unconditional: If the called extension has set Call Forward-Unconditional, PRASAR UCS
will forward the intercom call to the forwarded destination number. The call placed on the forwarded
destination will not be an Intercom call.
• Call Forward-No-Reply: If the called extension has set Call Forward-No-Reply, PRASAR UCS will not
forward the intercom call to the forwarded destination number on the expiry of the No-Reply Timer.
