Method of routing a data transmission

摘要

A method of routing a data transmission includes the first step of receiving a destination number of a data transmission. The destination number corresponds to a first communication network, e.g. voice grade analog telephone lines. In the second method step, a determination is made as to whether the data transmission should be routed through a second communication network, e.g. a digital network. In the third method step, the data transmission is routed through the second communication network if the second step so determines.
