Abstract:
A system for establishing a voice and signaling link through a PBX system from an remote telephone device includes a PBX system, a setless gateway, and an remote telephone device. The PBX system is coupled to a public switched telephone network (PSTN) via a trunk connection. The PBX system is also coupled to the setless gateway via a digital phone port, which includes a first bearer channel B and a second bearer channel B. DTMF tone sequences from the remote telephone device are decoded by the setless gateway, which acts as a proxy to the PBX system. The setless gateway routes voice and signaling from the second bearer channel B to the first bearer channel B , so as to extend the remote telephone device from the PBX system.
