Blink

Blink is an open-source real-time communications client for Windows. It uses the Session Initiation Protocol, commonly known as SIP, to support communication through compatible SIP services. Its software category is therefore centered on SIP-based real-time communication rather than general-purpose messaging. The open-source license identifies Blink as software whose source is available under open-source terms.

Blink can be used with many SIP providers, giving users a choice of compatible service arrangements. It can also operate on a local network through Bonjour. Users of SIP2SIP can use Blink with that free service as well. These connection options make it suitable for people working with provider-based SIP accounts, local network setups, or SIP2SIP.

MirrorNest distributes the official Blink build directly from its own storage. The mirrored build is scanned for malware before it is published. This distribution approach gives Windows users a catalog download that corresponds to the official build while adding a stated pre-publication security check. Blink fits MirrorNest as an open-source Windows communications application distributed through a direct mirror of its official release.
