absolutely amazing tech. amazing app on phone and desktop. It really did more than I could ever want at a good price. I was about to get 3 friends to sign up. until you find out if you have an android phone that you can not use the call waiting feature. so if you are on the phone in quo or just your personal line then you will not know anyone else is calling till they leave a voicemail or you hang up. ridiculous...

Great, feature rich app, that leaves a lot to be desired. Has ability to record all calls, but only within the app, not if call is forwarded to another phone through the menu, or if call forwarding is turned on. If you have the menu enabled there's no option to leave a message. Often times contact updates don't show up between devices. If you're on a regular call on your phone and an openphone call comes in through the app it still rings loudly. And it constantly drops calls...constantly.

Hi Cooper, thanks for your review. Unfortunately, if a call is forwarded, we no longer have access to that call, so we can't record it. It's sent to the new number. Also, regarding the call volume, that's specific to the level of the volume on your device. I'm happy to help troubleshoot these issues for you. Please reach out to support@openphone.co

We used this app for about a year and it worked pretty well with the occasional glitch. Their latest release, in addition to having some bizarre terminology and weird ergonomics, does not use the phone's proximity sensor on any of our staff's phones. This means that when you put your phone next to your ear, the screen doesn't turn off and your ear actuates functions on your phone. It's impossible to take a phone call and impossible to hang it up. This has been going on for weeks.
