Abstract: A method includes receiving a media signal at an interface device in communication with and disposed between an Internet Protocol private branch exchange (IP-PBX) and a first endpoint. The media signal is associated with the first endpoint and is associated with a session established between the first endpoint and a second endpoint within a session over internet protocol network. The session is established at least in part by the IP-PBX based on a session control signal received at the interface device from the first endpoint and sent from the interface device to the IP-PBX. The method also includes modifying the media signal at the interface device based on a per-device service associated with at least one of the first endpoint or the second endpoint.

Abstract: A telecommunication system for enabling a subscriber to calling features available by a central office to have access to such calling features when such subscriber is accessing the central office through either a line connected to the central office or an Internet, Intranet, Extranet (i.e., IP) network which uses the TCP/IP network protocol. The method includes the steps of: processing signals received by the central office from the subscriber through either the IP network or the line connected to the central office to determine whether the subscriber is placing a call to the central office through either the line to the central or through the IP network; and making such calling features available to the subscriber independent of whether the subscriber is connected to the central office through the line to the central office or through the IP network.

Abstract: In the development of development systems, efforts are being made to design software systems which are as modular as possible for controlling the switching system. Efforts are also being made to achieve this aim for the call processing system for controlling connections in a switching system. The basic structure of the call processing system has a signaling interface system and a call control system, both of which are limited to logic connection control and submit autonomous connection requests to a resource control system which carries out the physical connection control. The call processing system furthermore has a coordination system for coordinating the autonomous connection requests with respect to the resource control system.
