2) The application has an intelligent line detection engin that auto detects CSD/HSCSD and EDGE Support and

will auto adjust the settings in the backgound! Moreover the application picks the default voice settings

of your phone without the requirement to adjust voice to reduce Echo. The auto detect engine also has auto

A truly advanced sms and voice encryption product

3) All calls and SMS are encrypted with 256 AES, where you enter the Initializing Vector (IV) for calls and SMS.

4) All SMS are 256 bit encrypted and come to a secure Inbox, which is not available for view in the Normal Inbox of

your phone. The secure Inbox is accessible from inside the application which is password protected. No one can read

your secure Inbox without having a password to the application.

5) Encrypted Voice calls have a delay of 1.5 seconds only! Moreover, the Advanced buffering systems and noise reduction

algorithms ensure that there are a) No Echo, b) No background noises/static/disturbance and c) Crystal clear voice, NO

exceptions. We stand by this promise and quality to assure that none of the competitors can offer such voice clarity.

6) Voice calls require that the network should support CSD/HSCSD (both with EDGE Support). Even if your network has a low

data transfer rate, our software will auto detect that and send compressed voice between the handsets, thus ensuring that the

voice quality will not be deterred by the low transfer rate. This improvement also ensures that there will NOT be a delay of

more than 1.5 seconds even if network speed is slow.

7) No need to send us the phone to change the keys. Simply enter the key code yourselves and have full control on the software

and on your security. The recommended key size is 32 with as many special characters as possible to ensure the highest level of

security for a 256 bit encrypted Voice and SMS solution.

9) You can choose from an array of handsets that are compatible with this software. For details list of compatible handsets, click here.

10) This application is very easy to use and requires minimal setup to get it up and running. You don't need to enter any complicated

Network Settings, simply install and you are ready to go.

11) No call logs are available on the normal call log of the phone. All call logs are protected and can be viewed only within

the application, which is password protected. You have complete history of call logs, including date, time and duration. Simply

click on a log to call or edit the call logs as well.

13) All Copyrights and Source codes must be given to us. We need detailed informations about the development enviroment. We must be able to recompile the sources

in our company without any problems.
