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. 85 and “Configuration 
settings,” p. 86.
■ 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.
