Before you can use the PTT service, you must define the PTT access point and PTT 
settings.

In PTT communication, one person talks while the others listen. Speakers take 
turns responding to each other. Only one group member can talk at a time. The 
length of time of each turn is limited.

Phone calls always take priority over PTT calls.

Besides the packet data counters, the device registers only one-to-one calls in the 
recent calls lists in 

. The participants should confirm the reception of any 

communications where appropriate as there is no other confirmation of whether 
the recipients have heard the call.

To check availability and costs, and to subscribe to the service, contact your 
service provider. Note that roaming services may be more limited than home 
network services.

Many of the services available for traditional voice calls (for example, call 
mailbox) are not available for PTT communications.

Many service providers require you to use an internet access point for your default 
access point. Other service providers allow you to use a WAP access point.

For PTT service settings, contact your service provider.
