The system allows managing traditional voice and IP channels. It provides a full control of the communication process between the contact centre and the client as well as allowing processing incoming and outgoing calls made by the same agents.

When the signal comes, the telephone set rings a signal different from the standard ring tone call. After that the telephone temporarily switches off from the telephone line and works as an intercom.
