A system for routing Internet Protocol Network Telephony (IPNT) calls has a default router connected to a wide area network (WAN) for receiving and routing the calls, the default router having a set of default routing rules, and an intelligent router coupled to the default router. The default router, upon receiving a call, requests routing from the intelligent router, and routes by a returned instruction within a predetermined time. If there is no returned instruction in the predetermined time, the default router routes the call by the default routing rules. In a preferred embodiment the intelligent router is a router performing for a particular organization, such as a commercial entity, and may have access to a company database. In some embodiments routing destinations are call centers on premises of the particular organization or company, and the call centers may each be managed by a managing processor connected to the WAN, which may be the Internet.
