Too many glitches to be reliable.

The computer app works fine, and the phone system works fine but this mobile app for Apple will not except calls and cuts off calls prematurely if there is a second call or something else on your phone alerts you. I cannot believe in this day and age an app which was tested can have so many problems.

I cannot stress enough how terrible this app is. It is extremely glitchy and unreliable. My company just switched to another service because Onsip was so disruptive to our business. - If you are on a call and another call comes in, the app will often drop your current call- Calling extensions within your company often doesn’t work—the app won’t let you pick up the call, or one person won’t have sound. We resorted to just calling each other’s personal cell phones - We used to be able to do conference calls, or put a call on hold, dial a second person to request to transfer and give them details, and then transfer the call. A recent update to the app got rid of these essential functions we have been using for years. When we spoke to a customer service rep about it, they claimed that those functions never existed. - The “do not disturb” setting on this app only works some of the time, for no discernible reason. I had to resort to completely uninstalling the app on weekends and during vacation.Don’t waste your time. There are far better services out there.

Sometimes is the operative descriptor

Sometimes it works well, sometimes it does not. Sometimes it answers inbound calls, sometimes it does not. Sometimes it recognizes the Bluetooth headset attached to my phone, sometimes it does not. Sometimes it maintains a good connection, sometimes it can be very choppy and drop the connection, even if you are stationary and working over a Wi-Fi network as compared to moving and using a cellular network. In summary, I can only depend on this app sometimes. By contrast, my OnSip desk phones work very well. The Windows app is reliable, too.

Unreliable at best

Although I have this app on both my phone and computer, It has never worked well on either. 90% of the time I don’t receive any notification when I receive a call. Typically, the only way I’m notified is when I get an email afterwards saying a voicemail was left for me. I’m not sure I receive any indication at all of a call if the caller doesn’t leave a voicemail. Also, when I am able to get on the phone with someone, I’m often told that I sound scratchy that I’m cutting out. When I ca the same person back using my personal number all problems are fixed despite using the same device.I’ve tried logging in/out, updating the app, and just about everything else but nobody at my organization had been able to fix it or get it to work for themselves.Every once in a blue moon this app works as it should but it’s truly unreliable at its best and unusable at its worst.
