A communication management system operates with a packet switched local area network and includes a PSTN interface for communicating over a telephone line with a service provider central office. The system comprises means for establishing a logical channel over the packet switched local area network to support a real time communication session with a real time communication device in response to receiving session signaling from the real time communication device; means for controlling the PSTN interface to transition the telephone line to an off hook state in response to receiving session signaling; and translation means for providing digital audio over the logical channel, the digital audio representing a dial tone received on the telephone line from the central office and providing one of a plurality of dual tone multi frequency signals on the telephone line in response to receipt of data from the real time communication device corresponding to the one of a plurality of dual tone multi frequency signals.

Multimedia communication management system with line status notification for key switch emulation

The multi-media communication management system comprises a controller that interfaces with a plurality of communication space stations and with one or more communication medium service providers. The controller provides for multicasting or real time voice communications to selected recipients. To provide such multicasting, the controller receives a recipient list of subscribers to include in the multicast session. The controller identifies a communication space station serving a subscriber device associated with each recipient and invites such communication space station to the multicast session. If a recipient's subscriber device is not served by a communication space station, the multicast message is packaged as an audio file and sent to the recipient by e-mail.

Multi-media communication management system with multicast messaging capabilities

A desk top telephone includes a network interface circuit for audio session set up and audio session communication with a remote telephone device. A display device docking bay accommodates a simple display screen or a portable computing device such as a portable data device (PDA). Each of a plurality of adapters coupled one of the modular display screens or a PDA to the docking bay. Each of the module display screens and PDAs can have various display sizes, resolutions, and color/gray-scale combinations.
