Abstract
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.
