15. Push to talk
Push to talk (PTT) over cellular is a two-way radio service 
available over a GSM/GPRS cellular network (network service). PTT 
provides direct voice communication. To connect, press and hold the 
volume up (PTT) key.
You can use PTT to have a conversation with one person or with a group 
of people having compatible devices. When your call is connected, the 
person or group you are calling does not have to answer the phone. The 
participants should confirm the reception of any communications where 
appropriate, as there is no other confirmation whether the recipients 
have heard the call.
To check availability and costs, and to subscribe to the service, contact 
your service provider. 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. 80.
While you are connected to the PTT service, you can use the other 
functions of the phone. The PTT over cellular service is not connected to 
traditional voice communication, and therefore many of the services 
available for traditional voice calls (for example, voice mailbox) are not 
available for PTT over cellular communications.
