About push to talk
Push to talk (PTT) (network service) is a real-time voice-over-
IP service that uses the cellular 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.
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.
