Ratings and Reviews
No video on MAC
I bought this in hope for video support which is listened as feature on the website but it does not show up in the app on Mac. Disappointing.
No Audio on Sierra
Why is this non working app in the Appstore? It does not work on Sierra, no audio (mic or output). Sad!
Blink is a well-executed SIP client for Mac OS X
Having used many, many SIP softphones over the years, I tried an early version of Blink on OS X and thought it was a good first start but the implementation of the G.722 wideband codec was not too good, the client was somewhat buggy, and it ate up CPU resources on my MacBook Pro. However, I downloaded Blink Pro from the Mac App store and I'm very pleasantly surprised to see these problems have all been fixed.
Blink Pro is a solid, well executed SIP client. The audio quality is very good, and is actually excellent between phones that support the wideband G.722 codec. The SIP compatibility is excellent as it uses the well regarded open source PJSIP SIP stack.
It has strong integration into the OS X world. For example, it uses Bonjour for truly zero configuration setup for clients on a local area network. It also pulls in contacts from the Addressbook app.
Finally, there are a lot of advanced features including video conferencing and screen sharing. And I can see that there is plumbing in place for some really advanced features including secure SIP with TLS and SRTP, shared contacts with XCAP, and more.
With Family Sharing set up, up to six family members can use this app.
