Calling Basics
14
Call waiting
Call waiting lets you know that you are receiving an incoming call by
sounding a beep. For instructions on how to use call waiting, contact your
satellite or cellular service provider.
Three-way calling
Three-way calling allows you to talk to two callers at the same time. For
instructions on how to use three-way calling, contact your satellite or
cellular service provider.
Caller ID
Caller ID displays an incoming call’s phone number on the screen, if
available. If the phone number of the caller matches one stored in your
phone book, the name also displays with the number.
For more information on caller ID, contact your satellite or cellular service
provider.
Note
“Flash hook” is sometimes referred to when using call waiting,
three-way calling, or caller ID. This means quickly press and
release .
