Telstra aims to get push-to-talk technology that needed push with the launch
of the TalkNow ZTE 159 phone; a 3G tough phone built for the outdoors that
comes with an assisted GPS feature and a new Talk Now function that
instantly turns the phone into a walkie talkie.

The ZTE 159 is perfect all-around phone for manufacturing, trade,
construction, and even transport industries who have a lot of 'on the field'
users.
In addition to the AGPS function and Talk Now function, it also comes with a
Xora TimeTrack function that can track any device connected to your
'network' by logging in to the Xora website. By activating 'Shift Start' on
the mobile device, users will be logged on to the network and can be
immediately tracked down by any office supervisor or administrator who
visits the Xora website.

The Xora TimeTrack also allows a supervisor to schedule and/or dispatch jobs
for a mobile user. In this way, users can immediately download all assigned
or available jobs and see all the corresponding job details. It is also a 3G
unit that connects to Telstra's Next G network, providing users with
blistering uploading and downloading speeds.
