Abstract
A communication network includes a switching system, an application server, and a softswitch that communicatively couples the application server to the switching system. The switching system is configured to detect a first call to a primary directory number associated with a phone line and to forward the first call to the application server. The application server is configured to instruct the softswitch to generate a second call to a RingMaster directory number associated with the phone line. And the softswitch is configured to bridge the first and second calls responsive to detection of a communication path completion to the phone line.
Claims1
A method of operating a communication network, comprising:
- detecting a first call to a primary directory number associated with a phone line;
- forwarding the first call to an application server;
- generating a second call from the application server to a RingMaster directory number associated with the phone line;
- detecting a communication path completion to the phone line;
- and
- bridging the first call and the second call responsive to detection of the communication path completion.
Dependencies are inferred from the claim text.
