14. Push to talk
Push to talk (PTT) 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 device.
To check availability, costs, additional features and to subscribe to the service,
contact your service provider. Roaming services may be more limited than for
normal calls. This feature may not be available, depending on your phone.
Before you can use the PTT service, you must define the required PTT service
settings. See "PTT settings," p. 74. See "Configuration settings," p. 74.
PTT channels
PTT channel types
A PTT channel comprises a group of people (for example, friends or a work
team) who joined the channel after they were invited. When you call a channel,
all members joined to the channel hear the call simultaneously.
In a Public channel, every channel member can invite other persons; in a
Private channel, only the channel creator can invite others.
You can set the status of each channel to Active or Inactive.
