Blink6.0.3

Blink lets Windows users conduct real-time communications through compatible SIP services. It uses the Session Initiation Protocol, or SIP, so its purpose is SIP-based communication rather than general-purpose messaging.

Users can connect Blink to many SIP providers and choose the service arrangement that fits their needs. It also works across a local network through Bonjour, making it suitable for networked communication within an organization or home. SIP2SIP users can use Blink with that free service, alongside provider-based SIP accounts. These options serve people handling SIP communications through an external provider, a local network, or SIP2SIP.

AG Projects publishes Blink as open-source software for Windows on x86 architecture. Version 6.0.3 fixes requests for Sylk API tokens and corrects the updater, addressing two practical maintenance issues for current users.

Developers who build Blink from its source must compile all necessary dependencies. The project manages that source with the darcs version-control tool and also mirrors it on GitHub. Its related software includes Debian and Ubuntu Linux, Cocoa for Mac, a beta Qt6 Linux version, and Qt5 builds for older Linux releases.
