Abstract
The present systems and processes are directed to bridging telephone communications, such that a SIP communication server is able to communicate with the legacy PBX or key system interface for interworking connectivity of the devices. A bidirectional emulator module is provided permitting a communication session with legacy analog device and/or digital device. In certain embodiments, analog and digital telephones are registered with the emulator. An external telephone system such as a SIP communication server is also registered. A line dictionary contains the communication protocols of the analog and digital telephones and external telephone system. Outgoing line traffic and incoming line traffic are monitored in real-time, where the emulator module translates the user requests and line traffic according to the respective communication protocol data retrieved from the line dictionary.
