Abstract
A method for establishing a secondary communication channel between at least two computing devices over a network medium through use of a primary channel connects a first computing device with a first telephonic unit and a second computing device with a second telephonic unit. If the two telephonic units are in communication with each other over a primary channel, and communication channels are established between the computing devices and their respective telephonic units, then the first computing device transmits its location information to the second computing device over the primary channel. A connection is then established between the second computing device and the first computing device over a secondary communication channel.
