ContactPoint IP Phone
What ContactPoint IP Phone is
ContactPoint IP Phone is a Windows implementation of a SIP softphone. The project describes it as lightweight and supports Windows x32 and x64. To configure it, users provide a SIP account username and password, a realm, and a SIP registrar address; the maker’s example uses an Asterisk server address as the registrar. A customizable plugin architecture lets the software be extended, with a contacts book and calls log among the listed plugins. Calling tools include hot keys and OS-native click to call, and the software can trigger a browser when an incoming call arrives. It also supports advanced SIP headers for call-center use. ContactPoint is a desktop app, and Windows is the listed platform. The project is free and open source, and its GitHub repository lists the GPL-3.0 license. The repository references PJSIP pjproject and ComponentFactory Krypton. These details make the product’s core scope clear: SIP calling on Windows, with configurable plugins, contact and call-history tools, and support for call-center headers. The project website is ipphone.github.io.
