The system includes a server with a telephony management software (TMS) unit, a telephony application programming interface (TAPI) unit, and an application unit. The application unit includes a control module, association module, presentation module, park module, monitoring device interface module, and storage interface module. A server sends information to a monitoring device regarding the status of a monitored extension and calls offering on that extension. A server also enables a user to navigate through multiple calls offering and park a selected call."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Extension monitoring in a distributed telephony system","description":"A telephony system is presented that enables one user to monitor another user's extension and perform functions on calls destined for the other user's extension.
