I have connected 3 of my family members by this app to my Callcentric trunk (3 extensions). Took a few days to understand and polish the configuration but since then it works flawlessly for everyone in the family over android and iphone. A free account (under 10 users), hope it stays this way. Have a reminder to visit the admin console once in a while to keep it active

Pretty good app. I like just about everything. The only thing that is keeping me from giving it 5 stars is that when you receive a call then hang up your notifications still show an incoming call. It's not ringing or anything, it just shows like it is. It doesn't impact functionality, it's just annoying.

Works flawlessly. From registering the extension (I actually have multiple accounts from different phone systems) to calls, chats, managing voicemail. Just perfect! Never had an issue. Life changing untying from the office desk. And the support team is amazing too!

Android Apk not showing shortcut reply option for WhatsApp, please fix it.

Keep getting pop up notification on the mobile app" update required! Your server version is too old to connect to via this app." and to contact the admin, which I did but they can't find any solutions either. My app version is 20.4 and I have android phone and its version is 16. One UI version is 8
★★☆☆☆Taylor Fagan· Jan 30, 2026
It works I guess. The experience leaves so much to be desired. Biggest problems I've had are calls not ringing or if they do ring my entire phone audio output is stuck as call audio until I release all Bluetooth connections because the app doesn't communicate with the Android Audio APIs well, which is I guess the just of this review: the app doesn't work well.

2026 update (1-year anniversary from last rating): nothing was ever fixed from the last time you guys ruined this app and now, this NEW most recent update somehow sucks even more! Tell me why when I answer on the app on my phone it keeps ringing and vibrating as though someone is still calling in while I'm actively talking to them, and if I answer or decline this false call it shuts down the app?!? Please stop making already bad products worse. PS support hasn't helped with THIS one either.
