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.
