Method of Operation

The system will be comprised of a Linux Server, which will also be a Web server.

Clients will be able to login to the server via the Web in order to register, obtain pin number, and to perform administrative tasks.

The AudioCodes Mediant™ 2000 VoIP Gateway will be used as the PSTN Access Gateway (E1/T1 – PBX interface). The system architecture is based on IP, RTP and SIP for communication.

The platform is modular and can scale from 15 call back sessions for the enterprise market to thousands of sessions based on the same platform.

Incoming and Outgoing Calls

A trunk (E1 or T1) from the telephone company or the PBX will be connected directly to the AudioCodes Gateway.

This trunk will be used for incoming and outgoing calls to and from the system.

A set of DID numbers will be allocated by the system to subscribers calling the system.

Call Back Server Administrator

A system administrator with high priority privileges will be able to login to the system.

The administrator’s task includes maintaining the list of users allowed to use the system as well as updating system parameters .
