X-Lite is a free, lightweight softphone application for macOS (and other operating systems). It[SQ]s primarily used for making Voice over IP (VoIP) calls over the internet. It allows users to make and receive calls using a SIP (Session Initiation Protocol) account provided by a VoIP service provider. Think of it as a simple, basic phone app that works over your internet connection instead of a traditional phone line.

It[SQ]s considered "lite" because it lacks many advanced features found in more comprehensive VoIP clients. It[SQ]s generally suitable for individuals or small businesses needing basic VoIP functionality without complex features.
