The intercom feature lets you talk to someone on another phone that's connected to the same line. A person getting an intercom call will hear a special ring — two quick rings and a pause — to let them know it's an intercom call.

To make an intercom call:

  1. Pick up the phone and listen for a dial tone.
  2. Dial the 7-digit phone number.
  3. Hang up the receiver.
  4. The other phone(s) on the same line will ring — the ringing stops when another person picks up the phone.
  5. When someone picks up, the call connects.
