Plivo Call Center Application

This application is used to create a generic call center application using the Plivo platform. Agents can receive calls by going to /agent URL. When clients call the number assosciated with the Plivo Application, calls are forwarded to the agent. If there are more than one caller, they are put on hold until the call currently being handled is hung up.
