Push to talk
Push to talk (PTT) (network service) is a real-time voice
over IP service (network service) available over a GSM/
GPRS network. Push to talk provides direct voice
communication connected with the push of a key.
Before you can use the push to talk service, you must
define the push to talk access point and push to talk
settings. You may receive the settings in a configuration
message from the push to talk service provider.
In push to talk communication, one person talks while the
others listen from the built-in loudspeaker. Speakers take
turns responding to each other. Because only one group
member can talk at any time, the maximum duration of a
speech turn is limited.
Phone calls always take priority over push to talk calls.
