Push to talk
(network service)
Push to talk (PTT) is a real-time voice over IP service
implemented over a GSM/GPRS network. Push to talk
provides direct voice communication connected with the
push of a key. Use push to talk to have a conversation with
one person or with a group of people.
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 special text message from the
service provider that offers the push-to-talk service.
Press , and select My Own > Push to talk .
In push-to-talk 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 network operator
or service provider.
Warning: Be sure to hold the device in front of you
and not to your ear. The loudspeaker is used to
listen. Continuous exposure to high volume may
damage your hearing.
Phone calls always take priority over push-to-talk activities.
Define a push-to-talk access point
Many service providers require you to use an Internet
access point (IAP) for your default access point. Other
service providers allow you to use a WAP access point.
Contact your service provider for more information.
If you do not have a WAP connection, you may need to
contact your service provider for assistance with the first-time
connection or visit www.nokia.com/phonesettings.
