Push to talk (PTT) (network service) provides direct
voice communication connected with the push of a key.
With push to talk, you can use your device as you would
use a walkie-talkie.
You can use push to talk to have a conversation with
one person or with a group of people, or to join a
channel. A channel is like a chat room: you can call the
channel to see if anyone is online. The channel call does
not alert the other users; the users just join the channel
and start speaking with each other.
In push-to-talk communication, one person talks while
the other users listen through the built-in loudspeaker.
Users take turns responding to each other. Because only
one user can talk at a time, the maximum duration of
a speech turn is limited. For details of the speech turn
duration for your network, contact your service
provider.
Before you can use push to talk, you must define the
push-to-talk access point and push-to-talk settings. You
may receive the settings in a message from the service
provider that offers the push-to-talk service.
Phone calls always take priority over push to talk.
