| 1. A computer program product for use with a gateway to be used with a packet based voice system, the gateway connected to
a PBX and to a data network, the computer program product comprising computer executable instructions stored on a computer
readable memory, the program instructions when executed causing the gateway to carry out the steps comprising:
receive a call and query said call for a termination number;
use said termination number to determine a desired route for said call by determining if said call should be routed to the
PSTN, PBX, or data network; and,
determine if said desired route is available if said desired route is over the data network and transmitting said call over
the data network if said desired route is available, and to transmit said call over the PSTN if said desired route is not
available;
wherein the program instructions when executed further cause the gateway to:
use said termination number to determine if said call is:
an intra-company inbound call coming over the data network wherein a desired route is determined to be over the PBX;
an inbound leaking call coming over the data network wherein a desired route is determined to be over the PSTN;
an outbound leaking call coming from the PBX wherein a desired route is determined to be over the data network; or
an outbound call coming from the PBX wherein a desired route is determined to be over the PSTN.
