- Phones that are unstable because they have broken audio implementations:
Alcatel one touch series (poor audio drivers cause system freezes and crashes)
HTC one m8 (causes freezes.)
WARNING: using Zoiper as a default dialer may interfere with dialing 911 emergency services.
WARNING: Please use only versions from the appstore, we have reasons to believe some of the (russian) .apk files floating on the web contain a trojan that might steal username and password and make fraudulent calls. The official zoiper from google play is safe to use.

    Unreliable, won't send or receive calls after the app has been running for a few hours, requires a full device reboot to get the app to work again. Can't be relied on for business use.

    I'm really impressed! Had some teething issues related to the phone app and desk phone not ringing at the same time with incoming calls. Turns out it was a setting from my VoIP provider that wasn't enabled and I was unaware of. Seems to be working well now though! Kudos to the developer.
