13. 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 the volume up 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 people you are 
calling do not have to answer the phone. The participants should confirm the 
reception of any communication 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. 83.
While you are connected to the PTT service, you can use the other functions of 
the phone. The PTT service is not connected to traditional voice communication; 
therefore many of the services available for traditional voice calls (for example, 
voice mailbox) are not available for PTT communication.
