Blink
Blink is a real-time communications client that uses SIP to connect with SIP service providers, Bonjour on a local network and SIP2SIP. A SIP account from a service provider is required to use the client. Voice and video features include Opus audio, H.264, VP8 and VP9 video codecs, acoustic echo cancellation and ZRTP media encryption. Messaging supports MSRP chat, OTR encryption, SIMPLE presence and XCAP server storage. File transfers use MSRP and TLS and provide progress reports and delivery confirmation. Users can share screens with audio, and conferences can combine participant management, VoIP, messaging, presence, file transfer and screen sharing. Blink supports multiple SIP accounts, iCloud syncing between computers and built-in SIP account sign-up through SIP2SIP. The free plan is listed at 0.00 USD per free and includes Linux, Mac and Windows downloads. Feature availability can vary by operating system and version; some conferencing features require a conference server. Blink was founded in 2002.
Who it is for
Blink may suit people and organizations that already have SIP accounts and want voice, video, messaging and conferencing in one client. Organizations with more than 100 seats can ask AG Projects about demonstrations and integration support.
