Making and Answering Calls

Special default ring signaling is set for your telephone: 

When you receive an internal call, your telephone rings once every four seconds (single-tone sequence).

When you receive an external call, your telephone rings twice in rapid succession every four seconds (dual-tone sequence).

When you receive a call from the entrance telephone, your telephone rings three times in rapid succession every four seconds (triple-tone sequence).

If a call is waiting, you hear a short tone (beep) every six seconds.

The number or the name of the caller appears on the display.
