Abstract
A telephony to data re-routing system (TDR) re-routes telephony communication over a wide-area network (WAN) or over a Public switched telephone network (PSTN). The TDR is coupled to a PBX which is configured to route telephony data to the TDR. The TDR processes the telephony data by converting it to a form that can be transmitted over the WAN. The TDR can also re-route the data back through the PBX for transmission over a PSTN. The TDR maintains the traditional telephony interface of dialing in response to a dial tone. Using the TDR, telephony users gain advantages offered by WAN data transmission including store-and-forward delivery, optimized bandwidth allocation, and secure data transmission without having to learn a new user interface. In addition, multiple call originator telephone devices can use a single TDR.
