Abstract
A facsimile gateway provides fax transmission over a packetized network. To accommodate packet delay in the network, an alternate protocol source provides the appropriate notifications to the originating fax machine. In one embodiment, the gateway is constructed using conventional class II or 2.0 fax/modems and voice processing boards. The fax board provides most of the fax gateway operations. As needed, the voice board is switched into the call to provide notifications to prevent a time-out in the originating fax machine.
