Customer Reviews

Nice. Needs iphone 5 update. Long due

Needs update for iphone5 larger screen.
- keypad screen: when i click on back arrow to clear a number and finish clearing all numbers the ui changes and back button is no longer available. So i hit settings instead. Hope ui fix for iphone5 will give more screen space and this is rectified.
- why recent call shown in keypad. Confusing and wasting screen space. Use space for dialer instead.

Otherwise no issues and works good.

A update needed

Great app, lots off stuff, but an update needed for iphone 5 screen, and some stability improvement... and one more i would like to sea ... Its push notification incorporated :)

No caller ID

Pretty good VoIP app, for the price!

Only reason for 4 stars is that caller ID is missing. There is no way to register with your phone number and use authentication name with your regular user name.

Also would be nice if author gave a way to contact him directly.
