How a PTT call works
When you make a PTT call, you can instantly speak to
other Cingular PTT subscribers. During a PTT call only
one person can speak at a time. You can tell whether it
is your turn to speak by listening for the following
tones:
PTT Floor Held tone
This tone plays when you press and hold the PTT Key.
It indicates you have the floor and your speech will be
heard by the other call participants.
PTT Floor Release tone
When you let go of the PTT Key you will hear this tone
as will the other participants on the call. All of your
speech prior to this tone has been heard by other
participants. Others on the call are now aware that the
floor is open and they have an opportunity to speak by
pressing their PTT Key.
Error tone
If you attempt to speak by pressing your PTT Key and
someone else still has the floor you will hear this tone.
