Connection manager for integrating legacy telephony environments and IP networks

In a telephony call management system, a method of distributing calls among a plurality of packet-based load balancing resources can include receiving over a telephony channel a call request specifying call information, comparing the call information with selection criteria to select one of the plurality of packet-based load balancing resources, and querying the selected packet-based load balancing resource to resolve the call request. A response from the selected packet-based load balancing resource can be received which indicates whether the call request can be resolved.
