13. Push to talk
Note: This feature may not be available in your product due to
your subscription (network service).
Push to talk (PTT) over cellular is a two-way radio service available over
a GSM/GPRS cellular network (network service). PTT provides direct
voice communication. To connect, press the PTT key.
You can use PTT to have a conversation with one person or with a group
of people having compatible devices. When your call is connected, the
people you are calling do not have to answer the phone. The participants
should confirm the reception of any communication where appropriate,
as there is no other confirmation whether the recipients have heard the
call.
To check availability and costs, and to subscribe to the service, contact
your network operator or service provider. Roaming services may be
more limited than for normal calls.
Before you can use the PTT service, you must define the required PTT
service settings. See “PTT settings,” p. 90.
While you are connected to the PTT service, you can use the other
functions of the phone. The PTT service is not connected to traditional
voice communication; therefore many of the services available for
traditional voice calls (for example, voice mailbox) are not available for
PTT communication.
