Abstract
A networking system includes telephone switches and data network gateways for routing calls either over the public telephone network or over the packet switched data network. A router examines initiated calls and selects either the telephone network or a data network for completing the call. A Network Operations Center (NOC) monitors the performance of plural gateways, and updates routing information in the router and/or in the gateways, which may be used for future calls.
