** Android 5 with nexus 5 seems to cause microphone issues with Zoiper, we are investigating **

Zoiper is a FREE IAX and SIP softphone application for voip calls over 3G or WiFi. There are NO ADVERTISEMENTS.
Zoiper softphone offers a simple user interface and superb audio quality for smooth Voice over IP experience.

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.

Doesn't work with Nexus 5 The latest update to the app broke the mic functionality for Nexus 5s running lollipop, rendering the app completely useless. Will update review when the issue is fixed.

Areas for improvement: needs landscape on tablet; I already purchased Gold (on my phone) but the popup came up again on tablet (confusing); needs better GUI overall; would be cool if my SIP account info could sync between devices (phone, tablet, desktop). Good app overall though and voice quality has improved since last year.

Amazing & affordable with great features! I have been using this for a week now. The voice quality is too good. After trying so may other apps I found this as the best for calling abroad at very compromising price.
