Highlights
Eine sehr gute Sip Phone App
Best soft phone app out there now
Else this app is good for connecting VOIP calls
Best sip client on the store
Works fantastic with the Panasonic NS500 over wifi
Allows me full access to my Asterisk PBX when away from office
Works well on Verizon wireless service
Best app I have tried so far
Good quality sound and it works properly
Voice quality is so far good and usable app I have ever used before
Does not support display rotation
Downgraded star rating from 5 stars to 2 stars
Call waiting is not working properly either
The problems are the VoIP call log and native log are not separate
Then the same problem appears again
If people ring me they say I am too muffled to hear
But they all had some insurmountable failing
Now you have a separate app that is paid for
Don't force all your users into little boxes

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.
