A control process controls transmission of digitally encoded messages (DEMs) over a data communications network to allow real-time performance. The control process establishes a communication path which DEMs are sent. The control process can operate according to any data communications protocol, including the protocol native to the communicating device. The control process can establish communication paths based upon least-cost routing determinations. When there is insufficient bandwidth or excessive latency, the control process can choose a secondary path over which to transmit a DEM.

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.

A pro-active message delivery system which routes digitally-encoded messages via public-switched telephone networks and wide area networks to most cost-effectively deliver the messages, subject to security, privacy, and availability considerations. In a preferred embodiment of the invention, digitally encoded messages entered into a wide area network, either directly or via a public-switched telephone network, are sent to their destination using the most cost-effective route, by calculating the cost of sending the message via the available routes, and selecting the lowest cost route. Generally, the lowest cost route might use the node on the wide area network closest to the recipient of the message, or might use or node located in an area which charges off-peak rates at the time of transmission.
