When a call is in progress, press
MENU to open the call options.
Tap the available buttons on the
call options menu to put a call
on hold, dial another contact for
a phone conference, mute the
phone microphone, and more.
Note When the phone is dialing,
only the People and Speaker
on buttons are available.
