Ratings and reviews

Very intrusive, little options. Trying to use this when I work from home, but when I'm in the office near my desk phone there's no way to turn it off. Even when I force stop it sometimes calls will still come through. Also the interface is NOT user friendly at all. You can't even see a list of internal numbers when transferring calls, better know them by heart! Edit 2/25/25: The developers comment below is false. I changed it to silent, still causes my watch to vibrate and show up on my phone.

This is a frustrating app. My phone never rings. I'll get missed calls hours later. It has issues connecting to o my Bluetooth. Dialing numbers is extremely loud, but then the call volume is extremely low. I need to have it on speakerphone just to hear people while holding up to my ear. I tell people to just call my cell phone number instead of calling my office like because this app is so bad.

It works, and works well when it does. I currently have issues with this not ringing while DND is turned on, even when I have calls bypassing DND mode. Not sure why, but they just won't ring. Notification shows up, but no sound. Not even a vibration (with the setting on). Please, PLEASE fix this! Also, please split calls to queue calls and direct calls, if possible. I want queue calls bypassing DND, but if I'm not working and have DND on, I don't want people calling me directly and making my phone go off.
