Twinkle is written by Michel de Boer. The project started as a fun exercise to write a simple application that was able to setup a simple SIP call. Once that was working I kept adding to the project and it became a fully functional GUI based soft phone.
The SIP stack, call control, sound card control and GUI have been developed from scratch by myself. For the RTP stack and audio codecs I used 3rd party software.
Twinkle was originally available in english only. Since version 1.0 Twinkle has been translated to other languages.
