You can use your phone as an intercom to connect directly to another party inside your company.
Intercom call is different than making a regular call in the sense that it connects immediately. There is no ringing on the side of the recipient and he does not get a choice to answer or decline the call. But in order to give the him a notice about it, his phone will beep once before the call connects with the speakerphone enabled.
An intercom call will not go through if the recipient is on another call!
Note the distinction between the intercom feature (used inside an office) and the intercom functionality used with door phones and keypads (for communicating and access with people entering your office). You can read more about the later here.
To make an intercom call:
- When the phone is idle, press 7 on the dial pad.
- Enter the recipient’s number or extension.
- To end the call lift and put down the handset or press the Speakrphone button.
