Push to talk
Push to talk over cellular (PTT) is a two-way radio service
available over a GSM/GPRS cellular network. Push to talk
provides direct voice communication connected with the push
of the PTT key.
You can use push to talk to have a conversation with one person
or with a group of people having compatible devices. When
your call is connected, the person or group you are calling does
not have to answer the phone. Besides the GPRS counters, the
phone registers only one-to-one calls in the recent call lists in
Call
register. The participants should confirm the reception of
any communications where appropriate as there is no other
confirmation whether the recipient(s) have heard the call.
To check availability and costs, and to subscribe to the service,
contact your network operator or service provider. Note that
roaming services may be more limited than for normal calls.
Before you can use the push to talk service, you must define the
required push to talk service settings.
While you are connected to the push to talk service, you can use
the other functions of the phone. The push to talk over cellular
service is not connected to traditional voice communication,
and therefore many of the services available for traditional
voice calls (for example, voice mailbox) are not available for
push to talk over cellular communications.
