ABSTRACT:
A system and method allow PBX features to be extended through the public network. A teleworker calls into a PBX system and is assigned a fictitious port. The fictitious port is controlled by a telework server and appears to the PBX to be a local device. PBX features are invoked by particular sequences of DTMF tones or by voice prompt, or another data input system.
