Besides the packet data counters, the phone registers only one-to-one calls
in the recent calls lists in Log. 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.
Define a PTT access point
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.
Settings for PTT
For PTT service settings, contact your service provider.
To view and change PTT settings, select Menu > Settings > Connectivity >
PTT > Options > Settings > User settings or Connection settings.
User settings
Accepted list calls—To see a notification of incoming calls, select Notify. To

PTT call alert tone—Select the tone for incoming PTT calls. If you want the

using PTT.
