Abstract
A system and process for discovery between endpoint components and computing devices residing at remote locations from each other, in cases where the devices are connected to a common computer network, is presented. The present invention allows a device in one location to discover the network address of another device at a different location, which then allows the first device to negotiate with the discovered device to facilitate the transfer of data and other communications over the common network. However, this discovery is accomplished without the use of the common network. Rather the discovery process uses audible or inaudible audio signals transferred between the devices at two different locations using a communication medium, such as a telephone system.
