Answering a call
Your OpenScape Desk Phone CP400T phone rings with the tone signal set
when an incoming call is received. The call is also visually signaled on the call
display.
• When you receive an internal call, your telephone rings once every four sec-
onds (single-tone sequence).
• When you receive an external call, your telephone rings twice in rapid succes-
sion 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.
If transmitted, calling party information (name, phone number) appears on the
graphic display.
