Abstract: A system and method for providing PBX-like functionality at a mobile location includes the capability of maintaining a network session with a mobile number associated with a remote worker. The system utilizes a remote office platform interposed between a data communications network and a conventional PBX switch. A remotely located individual (such as a telecommuter) “logs in” to the remote office platform and, once the individual is authenticated, PBX-like communication with the mobile device is established. If the device is a computer-enabled device and includes a display, the platform can enable a graphical user interface emulating a PBX station set to the device. Alternatively, the remote worker can enter either spoken commands or series of DTMF sequences to utilize the PBX-like features. For these applications, the remote office platform includes a speech recognition module and a translation table for converting a sequence of DTMF tones into a PBX-like call feature (e.g., transfer, hold, mute, etc.).

Abstract: Architecture for bridging unwanted calls back to the PSTN (public switch telephone network) thereby freeing-up enterprise ports for other uses. When an incoming PSTN call is received into the enterprise via the PBX, a SIP server makes the decision to trigger bridging after obtaining the call reference and the interface on which the call exists. The SIP server sends a request to the PBX to trigger bridging. When the PBX determines it no longer needs to be involved, it sends the bridging request to the PSTN. More specifically, a mechanism is provided to trigger TBCT (Two B-Channel Transfer) from the SIP server thereby pushing call routing of unwanted calls out of the PBX and preserving PBX ports. The SIP server can retrieve the PSTN-related information from the PBX using either web services or a SIP-based protocol.
