Push to talk (PTT) over cellular is a
two-way radio service available over
a GPRS cellular network (network
service).
You can use PTT to have a
conversation with one person or
with a group of people (channel)
having compatible devices. While
you are connected to the PTT service,
you can use the other functions of
the phone.
To check availability and costs, and
to subscribe to the service, contact
your network operator. 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. 56 and ”Configuration settings”
p. 57.
■ PTT channels
A PTT channel comprises a group of
people (for example, friends or a
workteam) who joined the channel
after they where invited to. When
you call a channel, all members
joined to the channel hear the call
simultaneously.
There are different types of PTT
channels:
Public channel — Every channel
member can invite other persons.
Private channel — Only persons
which receive an invitation by the
channel creator can join in.
Provisioned channel — A permanent
channel is created by the service
provider.
You can set the status of each
channel to Active or Inactive.
The number of active channels and
the number of members per channel
is limited. Contact your service
provider for details.
