    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. If you want all features without paying, don't pirate it but ask your friends for the unlocking cheatcode instead. First rule about the gold club: don't publicly publish the cheatcode, but share it privately at will.

    Good app, but I would prefer if this app and the dialer would not share call history

    The new UI plain sucks, especially the very confusing Account Setup just to connect to an Asterisk box.

    When a call comes in and I attend, it says "Normal Remote Hangup" and disconnects. I am not able to talk. I am using a VPN to connect to my office network. I send an email to support but no reply.

    The previous version worked a little bit smoother on my Samsung Galaxy S8 Plus Now with this new version my accounts that I have loaded on is giving me a lot of problems by not registering on my mobile network and struggle to connect with Wi-Fi is there a way not to update it and get back the older app
