Matrix NAVAN CNX200 System Manual 1049
Intercom
The Intercom feature of NAVAN enables extension users to connect quickly with any desired extension, without
waiting for the called extension to answer.
• NAVAN will serve an Intercom call made by an extension only if:
•
the called extension is a SIP Extension (Matrix Extended IP Phone or Open SIP Phone).
• 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
Open 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.
• On SIP extensions, NAVAN supports Intercom using Call-INFO / Alert-INFO Message, enabling
interoperability with IP Phones of Cisco, Grandstream, Snom and Yealink.
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.
• NAVAN 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, NAVAN 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, NAVAN will reject the Intercom call.
• Call Forward-Unconditional: If the called extension has set Call Forward-Unconditional, NAVAN 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, NAVAN will forward the
intercom call to the forwarded destination number on the expiry of the No-Reply Timer.
• Call Forward-Busy: If the called extension has set Call Forward-Busy, NAVAN will place the call on the
forwarded destination number. However, this call (placed on the forwarded destination) will not be an
Intercom call.
