WARNING: using ZoiPer as a default dialer may interfere with dialing 911 emergency services.

Ratings and reviews

Overall the app works well but it requires a degree in Voip technology to get it set up. My biggest disappoint was paying $12 to upgrade to the pro package to get better voice quality and battery usage only to find out that there was yet another in App purchase for the option to truly get decent battery optimization. Very expensive app and misleading marketing.

EDITED: Not sure what is wrong: when I call using a headset (I tested 2 wired and 2 Bluetooth on 2 different phones), the other parties invariably gets very choppy voice. Tested between my own phones - indeed, my voice cuts in and out. No idea which setting - tried echo cancellation, tried microphone boost, tried all codex. Everything is perfect without headsets. Any ideas?

1. Push notifications have never really worked on the Android application, other products work without issue 2. Call integration not updated to offer newer options like redirecting outgoing calls via the application (and support's response doesn't seemt to want to look into it ) 3. Asking for short registration time error message to be disabled on the client as they interrupt the users experience was met with, this-is-a-you problem. There seems to be disinterest in modernizing this product.
