Basically useless

The app will NOT receive calls if your iPhone is locked or the app is just running in the background. It also behaves differently depending on whether the phone is using the cellular network (works) or wifi (receives calls 50% of the time). It has no use if my staff cannot reliably take calls from the lock screen as with a normal call or a Skype or Whatsapp call. Please tell me you can fix this.

Problematic but can work OK with a bit of hacking

This app does deserve its one-star rating for having gone so long without any update or even transparency regarding a frustrating inability to receive calls to a locked/sleeping iPhone but I have found a reliable workaround for this if you have a mobile phone number to use.

Within the settings menu of the app itself, make sure you have ALL Call Forwarding options enabled EXCEPT “Always Forward”. This will cause all incoming calls to the VOIP number to be redirected to a mobile phone if the VOIP line is unavailable. This process does not disclose the forwarded number to the calling party—that will remain private.

This will not work if the device using the app does not have a mobile phone number associated.

Feeling a strong 2 to light 3 on this app. Definitely needs this incoming call issue to be rectified ASAP. Also lacks some other rudimentary functions like being able to copy/paste a phone number to call. Hard to believe that this is being rolled out by big corporate telecommunications, go figure.

Can’t receive calls unless app is open

As the other comment mentioned, this app is unfortunately useless as incoming call alerts don’t work unless you actually have the app open and in focus on your phone. This has been broken a long time now, would very much appreciate a fix ASAP.
