Abstract
Systems, methods, devices, and non-transitory storage media provide a web-based graphical user interface to allow a user to control a softphone of a user device. A context handler operates on the user device and manages a page context of the web-based graphical user interface. A call manager operates as a RESTful web service on the user device. The context handler and the call manager communicate using JavaScript Object Notation with Padding (JSONP) messages. The call manager includes a finite state machine that indicates a current state of the softphone. The call manager generates application programming interface calls to the softphone in response to receiving JSONP messages. The user interface is updated to reflect the current state of the softphone based on execution of user selections by the softphone. The context handler chunks data into multiple JSONP messages if data exceeds a data size limitation of the JSONP.
