What Can I Do During A Call; Switching Between Calls - HTC Rezound User Manual

48 Phone calls
HTC Caller ID
Everytime you make a call or your friend gives you a ring, you get to see your friend's
latest status update from social networks like Facebook or Twitter right on the call
screen. You also won't miss people's birthdays. You'll see a birthday reminder, if your
friend's birthday will occur sometime within the next seven days.

What can I do during a call

When a call is in progress, use the buttons onscreen to mute or unmute the
microphone or to turn the speakerphone on or off. You can also press MENU and
choose other options such as muting the microphone, and more.

Switching between calls

If you're already on a call and accept another call, you can choose to switch between
the two calls.
1. When you receive another call, tap Answer to accept the second call and put
the first call on hold.
2. To switch between the calls, tap the person you want to talk to on the screen.
