Qtalk secureServer allows secure, encrypted telephony via data channel. The Qtalk secureServer consists of two elements
- a server with Qtalk software and database as well as
- software clients for smartphones
The Qtalk secureServer can be integrated seamlessly in existent infrastructures and allows for the first time a telephony without needing a 3rd party hosting.
The software clients thereby communicate among themselves through an own server and are, despite using data networks of mobile providers (access via EDGE, UMTS, HSPA or Wi-Fi), applicable in order to transfer contents tap-proof and problem-free.
Qnective therefore allocates the software for smartphones (software clients) as well as the adequate preconfigured hardware (server). Clients are available for diverse smartphones and can be used independent from the mobile provider.
