Call Waiting
Using Call Waiting
Call Waiting is a service for placing the current call on hold
and answer a new incoming call when the handset beeps
during a call to notify you of another call. In addition, place
the current call on hold and make a new call.
To use Call Waiting, set "Arrival call action" (nP. 379) to [Answer]
in advance. If set differently, answering a new incoming voice call
during a voice call is not available even if Call Waiting is activated.
