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. 87 and Configuration settings p. 88.

Push to talk 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.
