Absolutely HORRIBLE
We used Clarity Connect until forced to change to Ultatel Hub in December 2022. Since then this app has been totally useless and unreliable . Freezes each time we get a call, unable to answer calls on the mobile app, the app continues to ring after the calls are answered on our desk phones. Doesn’t display the call history correctly. Won’t log out. We have to uninstall and reinstall the app to log out. Customer support has us uninstall and reinstall, then makes a test call that works and then closes the support ticket. Their last suggestion was to get rid of the IPhone and get an android. My solution is to find another phone company that will be reliable.
