About push to talk
Push to talk (PTT) (network service) is a real-time voice-
over-IP service that uses a GSM or GPRS network. PTT
provides direct voice communication, with the push of
a key. Use PTT to have a conversation with one person
or with a group of people.
Before you can use PTT, you must define the PTT
settings (access point, PTT, SIP, XDM and Presence). You
may receive the settings in a special text message from
the service provider that offers the PTT service. You can
also use the Settings wizard application to configure
PTT, if supported by your service provider. For more
information on the PTT application, see the user guide
for your device or your local Nokia website.
In PTT communication, one person talks while the
others listen through the built-in loudspeaker.
Warning: Do not hold the device near your ear
when the loudspeaker is in use, because the volume
may be extremely loud.
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. The
maximum duration is usually set to 30 seconds. For
details of the speech turn duration for your network,
contact your service provider.
Phone calls always take priority over push to talk
activities.
Log in and exit PTT
When you start the push to talk (PTT) service, you are
automatically logged in and connected to the channels
that were active the last time you closed the
application. If the connection fails, to attempt to log in
again, select Options > Log in to PTT.
To exit PTT, select Options > Exit.
To switch to another open application , press and hold
the menu key.
