Zoiper Click2Dial is a Firefox extension designed to enhance communication by turning phone numbers on web pages into clickable links. This subscription-based tool enables users to initiate phone calls directly through the Zoiper application, streamlining the calling process. The extension offers several configuration options, including the ability to enable or disable it on specific websites or pages, as well as settings to show or hide the Zoiper logo and country flag next to phone numbers. Additionally, it features a region selector to assist in recognizing numbers without prefixes and a blacklist option to restrict its functionality on selected sites.

The extension also includes a convenient context menu feature that allows users to select any text or number on a webpage or within a CRM and initiate a call with a simple right-click. However, it is important to note that the Click2Dial extension requires an official paid license of Zoiper to function, ensuring that users have access to all its features and capabilities.
