Cordialtech - Know your VoIP pulse (Calling card and ANI Authentication and billing software)

| | | |

SIP and RTP proxy, IVR engine and billing.

This combined product by CorDialTech handles SIP signalling requests as well as creates a framework for call session management, plus includes RTP proxying and some useful elements of a softswitch. We have optimised it for running on a standard PC with Linux. The SIP server also complies with the standards laid down in RFC 3261.

While routing VoIP traffic, our software anonymises it. Namely, the communicating parties cannot trace each other since the proxy employs masquerading. This is a necessary step to keep your business data (such as routing, costs) completely confidential.

SIP proxy comes with a web interface - your control panel for administrating and billing the customers.
