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”

.
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.
