Responding to Call Waiting
When you’re on a call, Call Waiting alerts you to incoming
calls by sounding two beeps. Your phone’s screen informs
you that another call is coming in and displays the caller’s
phone number (if it is available and you are in digital mode).
To respond to an incoming call while you’re on a call:
ᮣ Press . (This puts the first caller on hold and
answers the second call.)
To switch back to the first caller:
ᮣ Press again.
Tip: For those calls where you don’t want to be interrupted, you can
temporarily disable Call Waiting by pressing * 7 0 before placing your call.
Call Waiting is automatically reactivated once you end the call.
