Set up Third-party Integration for Call Popup

Yeastar Popup URL allows a lightweight integration with a third-party application (such as CRM system, ERP system, etc.) to achieve call popup. When an extension receives a call, the PBX calls the URL of the third-party application and retrieves relevant customer data to display on the pop-up web page.
