Abstract
A call manager includes a first device process that controls a first telephony device and that receives a call request from the first telephony device. The call request includes a telephone number associated with a second telephony device. The call manager also includes a call control module that receives the call request from the first device process, and the call manager further includes a route list control process that is associated with the telephone number and that receives the call request from the call control module. The route list process accesses a route list to determine a port of a gateway device that can transmit the call request to the second telephony device. The route list process communicates the call request to a second call manager that is coupled to the packet-based network and that controls the gateway device included in the route list.
