Abstract
A method and system for routing a call at least partially over a packet switched network is provided. The method comprises receiving the call at a network operations center in communication with a server, and sending a first query from the server to the gatekeeper. The gatekeeper sends the second query over a signaling network to a service control point in response to the first query. A routing message is received at the gatekeeper from the service control point in response to the second query. The routing message is communicated from the gatekeeper to the server, and the call is routed to a call destination in accordance with the communicated routing message. The call is at least partially routed over the packet switched network.
