Ratings and Reviews
Solid SIP Client
I've been using Blink Lite for quite some time now and really satisfied. It's also comes at the right price (free). The client has a wide list of codecs available (G.729 is the only missing but that never comes for free) HD Voice & Video calling, IM and Presence capabilities. Perhaps my favorite feature is OS X Address Book Integration.
I'm giving it four stars because there's no echo cancellation. If you are talking to someone on speaker they will hear their voice, so it is better to use a headset. Overall, it's a solid and stable SIP client, never had a problem with it. It's not obstructive and has a decent GUI. Can't ask for more.
Nice UI, Address Book integration, and it works
Blilnk Lite is a SIP client that actually works for me. It has (contrary to other reviews) a dialpad, good connectivity, and a nice streamlined interface. I'm using callcentric and it was straightforward to set up. Great integration with Address Book which for me is simply required. Decent price. No complaints, but all I want is a multiline business phone and don't really need the the extra features available on Blink Lite's big brother, Blink Pro.
Please just add the ability to auto-pause itunes when receiving/making calls and it would be really nice if it also could totally stop other audio from coming through the speaker/headphones when on a call. I hate hearing other apps audio alerts when on calls.
With Family Sharing set up, up to six family members can use this app.
