Blink is a Session Initiation Protocol (SIP) client distributed under the Blink license (GNU GPLv3 with an exception to permit the inclusion of commercial proprietary modules). [4] [5]
The software is written in Python for macOS's Cocoa, with a later port to Qt for supporting Microsoft Windows, Linux, AmigaOS. [6] [7]
Blink is based on the Session Initiation Protocol, and beyond voice over IP, its features also include video, instant messaging, file transfer and multi-party conferencing sessions based on MSRP protocol, remote desktop sharing using RFB protocol (VNC), and SIMPLE presence using XCAP protocol. Compatible with Asterisk. [8]
