You can use the Hotline Intercom feature in a boss and secretary environment where two people can communicate through the speaker by pressing the Hotline Intercom button.
Configure phone A with HOT I key and specify the target DN as phone B and a mode; for example, Voice or Ringing. Similarly, configure the target phone B with HOT I key and specify the target DN as phone A.
When a user presses the Intercom key, the target phone auto-answers the call after providing a ring tone.
The prime DN is the CLID.
Communication Manager endpoint user experience
Automatic intercom is a feature where a button is administered. When a user presses the button, a call is place to a predefined extension. An intercom call makes a unique alerting sound. If the desk phone has an intercom button with a status lamp, the lamp flashes.
To control which users can make intercom calls to each other, an administrator can add the desk phones of the users to a group called "intercom group." After the administrator adds the desk phones to the group, users can make intercom calls by administering an automatic intercom button on their desk phones.
Device Adapter endpoint user experience
The Hotline Intercom feature in Device Adapter adds the auto-answer capability to the existing Hotline two-way feature.
Configuration and user experience are almost the same as that of CS 1000. Device Adapter provides an additional HTLI mnemonic to auto-answer a call.
Hotline Intercom uses a bridged appearance and the enhanced HTLI mnemonic to auto-answer inbound calls and auto-dial the hotline number that is configured for the Device Adapter endpoint. Administrators can use the HTLI mnemonic to the specify the Caller ID (CLID) for which auto-answer must be enabled. If the CLID filter is not specified, Device Adapter auto-answers all inbound calls.
