How does Push to Talk work ? |

Push to Talk (PTT) is like turning your mobile into a walkie talkie but
with a global range. Instead of transmitting/receiving radio frequencies, Push to Talk
uses the GPRS data connection on your mobile to send and receive calls using
VOIP technology.
Keep your mobile network
No need to change network as we're plugged straight into the O2, Vodafone and
Orange networks. Push to Talk is added to your mobile’s functions without changing your
current supplier. We change the configuration of your GPRS settings (namely the
APN) so that there’s no delay between your PTT chat because priority is given to
our data for voice. Also it means there’s no drain on your battery.
Keep your handset
There’s no need for new equipment as Push to Talk works on most Nokias and HTC handsets.
New handsets are constantly being added to the list that will support our Push
To Talk service. To see the range of PTT compatible handsets click here
Data usage
You will have to pay data charges to your current mobile operator, so you need
to check what data package you currently have with them. But we’ve managed to
compress the data needed for voice to only 1kbps, And data is only used when
you’re speaking but not for any elapsed time during a conversation, so we
estimate an average of 20Mb is required per month.
How do I get PTT?
- We text you softare that embeds itself into your mobile.
- The software automaticaly links to your contact group and sets up the PTT
button.
- Press your PTT button, wait for the beep, then begin to speak.
- Your message can be heard by everyone on your contact list.
- IF you want to speak someone individually, just select that persons name from
your contact list and press your PTT button to talk
-Remember, whoever is pushing the button is the speaker

PC Client
The PC client allows office-based staff to stay in touch with field staff direct
from their PC. This allows close integration and co-ordination in a way that
would not be possible on a traditional RF system.
Internet Packet Radio System
(IPRS) Server
The IPRS server handles all the Push to Talk call routing. It manages all the user and
groups settings on the PTT service and routes 1:1, group and “ad-hoc” conference
calls.
Network Management System
(NMS) Server
The NMS is used to control the IPRS server, including the creation of new
customers, adding/removing/edit user accounts, and creation of user groups.
Mobile Operator Access Points
(APN)
The APNs are gateways between the mobile GPRS (data) networks and Push To Talk
Communications Ltd. End-users configure their Push To Talk mobile to use the Push To Talk
Communications Ltd APN, which provides an IP path between the PTT back-end
infrastructure and the Push To Talk client on the mobile handsets.
PTT Handsets
Many current GSM handsets are Push to Talk capable and require little or no modification.
User’s handsets are provisioning automatically using SMS messages sent from the
Push To Talk Communications Ltd PTT provisioning system |
