■ Push to talk
Push to talk (PTT) (network service) is a real-time voice over IP service (network
service) available over a GSM/GPRS network. PTT provides direct voice
communication connected with a single keypress.
Before you can use the PTT service, you must define the PTT access point and PTT
settings.
In PTT communication, one person talks while the others listen. Speakers take
turns responding to each other. Only one group member can talk at a time. The
length of time of each turn is limited.
Phone calls always take priority over PTT calls.
Besides the packet data counters, the phone registers only one-to-one calls in the
recent calls lists in Log. The participants should confirm the reception of any
communications where appropriate as there is no other confirmation of whether
the recipients have heard the call.
To check availability and costs, and to subscribe to the service, contact your
service provider. Note that roaming services may be more limited than home
network services.
Many of the services available for traditional voice calls (for example, call
mailbox) are not available for PTT communications.
Define a PTT access point
Many service providers require you to use an internet access point for your default
access point. Other service providers allow you to use a WAP access point.
Settings for PTT
For PTT service settings, contact your service provider.
To view and change PTT settings, select Menu > Settings > Connectivity > PTT >
Options > Settings > User settings or Connection settings.
