• Use call waiting
If you have call waiting, your phone beeps during a call to let you know
that someone else is calling you.
Depending on your caller ID setup, the phone might also display the
number of the incoming call.
Note:
Call waiting may not be available in all wireless systems.
Contact your service provider for details and availability.
Before you can use call waiting, you must first store its feature code.
Then you must activate the call waiting feature.
