Abstract
Voice calls between two end location gateway servers of a data internetwork are diverted, during periods of unacceptable network conditions, through the public switched telephone network (PSTN). A plurality of such diverted calls may be multiplexed into a single ISDN or T1 channel, thereby permitting a sharing of the more expensive cost of PSTN routing. Incoming calls are appropriately formatted for digital transmission, including compression when applicable, by the gateway servers and multiplexed for transmission either through the data network or back through an ISDN channel or the like through the PSTN. Calls may be expeditiously re-routed back through the data internetwork when data network conditions improve.
