Connectivity
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 device 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.
