Introduction
According to our observations there is an emerging demand both from the sides of governmental institutes and companies operating in the commercial sector for the encrypted communication, using public networks. The main goal is the secure transmission of classified information, no matter if it is verbally spoken, multimedia, or data communication. Furthermore the headquarter needs to have the ability to monitor and intercept the secure communication.
Above the communication features the secure access to corporate applications and mailing is also a basic requirement. During these types of transmissions, the information must not get outside the trusted environment or be saved on the client terminals.
There are existing products on the market that are partly able to handle some of the above-mentioned needs but NETIPHONE™ is directly designed to deliver all these required functions. On top of that NETIPHONE™ is a user friendly, easy-to-use application with plenty of useful tools that makes communicating through secure channels as simple as the everyday mobile telephony.
System overview
NETIPHONE™ provides trusted communication through the encrypted data channel between the mobile client and the central NETIPHONE™ server, using public mobile data network.
The central VoIP server provides the secure verbal communication between the connected terminals. Secure mailing and usage of central services – e.g. file transfer – are also available by the NETIPHONE™ system.
Intercepting the secure communication and monitoring the usage of the system according to system logs is also a basic feature of NETIPHONE™.

Advantages of the system
Bearer independent encrypted channel – voice, media, data
NETIPHONE™ is able to provide encrypted voice, media and data communication as well as access to central applications at the same time. Furthermore the system is able to operate on any data communication channel that fits the minimal system requirements (e.g. channel quality).
Central functions
Since the system communicates through a central server it is possible to manage and monitor the communication centrally and also to apply server based applications.
Due to centralized functions, the sensitive data that is crucial for the operation of the system is stored on secure storage
User-friendly interface
The remote desktop application of NETIPHONE™ has a simple user interface that provides basic functions. It is optimised for the display of mobile phones.
Separated public and closed telephone functions, common resources
NETIPHONE™ can be installed on normal commercial mobile phones it does not require any special appliance. The encrypted voice communication will immediately be suspended in case of an incoming open network call. After the dismissal or termination of the open network call the system returns to the encrypted communication automatically.
