Today there is no solution for telephony architecture which allows the new multimedia transport and signaling techniques the use of individual terminals without the loss of existing telephony features that are still provided by installed PBX (Private Branch Exchange) and moreover that is open enough to allow the gradual addition of new features, services and applications in a true, network-independent way. The new telephony service architecture resolves these restrictions by introducing an open service control plane, uncoupled from the basic call control and media planes. Furthermore this solution allows the full use of PBX functionality towards old and new terminal types.
