Intercom is a user level feature available for compatible One Talk Desk Phone models. The feature is enabled by the end user on each Desk Phone as opposed to a setting in the One Talk portal.

Once enabled, customers using compatible Desk Phones can place direct calls from their One Talk extensions to other One Talk extensions. When the phone call connects to a receiving One Talk Desk Phone, the call is automatically answered by the speaker phone, allowing the parties to immediately begin a 2-way conversation.
