Ratings and reviews

What I like about this app is how it integrates with my contacts. The app gives me the option to dial a contact either from my cell phone or through my VoIP via the app - very cool! However, I have to subtract 3 stars because on the latest version which I installed there is no keypad, and all the other tabs for call Log, contacts, and groups are also missing. 3rd UPDATE: just tried reinstalling the app again but the same problems remain. Had to return back to ZoiPer.

Not sure why some knock this app. It's clean, simple, lightweight and reliable. Works well with both my upstream provider and my own home grown solution. Even offers features usually only found with "premium" VoIP clients. Even run this on older, low ended Android with limited memory as it's not bloated. Thanks dev! Stay safe and keep up the great work!

Great app that I intend to use with desktop Sipgate (the two seem to synchronise well so far) BUT a major problem is the ringing tone. When a caller calls my (VOIP SIPGATE landline) number they hear what is an engaged tone in UK/Ireland and not a ringing tone. This is causing confusion and resulting in callers hanging up. Fix this and the app is great and will awarded 5 stars!
