1. The app is very inconsistent in showing whether an incoming call is from one’s 8x8 phone number vs a call direct-dialed to one’s mobile number. I have played with the settings for incoming calls over data vs cellular voice and there seems to be no consistent pattern to the results. 2. When incoming calls *do* identify as being via 8x8, they are impossible to answer before going to voicemail if one is at the lock screen. That is, unless the phone is active and the 8x8 app is in front, there are too many actions required to answer the call in the time allotted. 3. The app inconsistently shows my correct caller ID vs. showing “anonymous” to those I’m calling. 4. At times, ringer settings don’t function at all. (I have had the experience that incoming calls via 8x8 ring very loudly, even though I have set the app and the iPhone itself to vibrate only). Overall, this is an amateurish app and 8x8 doesn’t seem interested in learning and improving.
