Call Waiting
Description During a conversation, a call waiting tone notifies the user that
another incoming call is waiting. They can answer the second call
by disconnecting or placing the current call on hold. The call
waiting tone can be activated or deactivated by dialing the
appropriate feature number.
Conditions • A call waiting tone is generated when an outside call (except a
doorphone call) is received, or when an extension caller executes Busy
Station Signaling, if Call Waiting is enabled.
• Setting Data Line Security temporarily cancels Call Waiting which has
been turned on by an extension user.
• For proprietary telephone users, two types of call waiting tones are
provided.
A proprietary telephone user can select the desired type by station
programming.
• Tone 2 depends on the assignment in program [423] “Outside (CO) Line
Ringing Pattern Selection” for outside (CO) lines and program [115]
“Extension Ringing Pattern Selection” for intercom calls.
