to set the phone to use the loudspeaker or headset for
PTT communication.
Warning: Do not hold the device near your ear when the loudspeaker is in use, because the volume may be
extremely loud.
When connected to the PTT service, you can make or receive dial-out calls, channel calls, or one-to-one calls.
One-to-one calls are calls you make to only one person.
