Description
While in conversation, a call waiting tone informs the user of
another incoming call that is waiting. He or she can answer the
second call by disconnecting or placing the current call on hold.
Call waiting tone can be enabled or disabled by dialing the
appropriate feature number.
Conditions
• The call waiting tone is generated when an outside call or a doorphone
call comes in or when an extension caller executes Busy Station
Signaling.
• 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 tone are
provided to prevent them from missing the tone as shown below:
A digital proprietary telephone user can select the desired type by
station programming.
