Thank you for your review.

Much better than Skype

UK guitar fan

We used Skype for about 5 years, very unhappy with the quality and reliability. I was starting to wonder why Skype hadn't improved, or another company become more popular. In the in I started doing a bit of reading and discovered that instead of Skype and a poor selection of 'Skype phones' there is the SIP standard for voip with various compatible phones, softphones and providers. I signed up to voipfone, bought Siemens gigaset phones and this softphone. It all works brilliantly. Even making VoIP calls over 3G works well. Incoming calls ring immediately on my iPhone, unlike the Skype app which rings after a long delay or not at all. My experience of VoIP and sip is nearly as good as using a landline. I guess with Microsoft and eBay owning Skype there wasn't much hope of it becoming a decent service...

Best VOIP Client around


I have tried them all skype truphone fring and many others this tops them all ok you have to pay for the app but you are not locked into phone providers I use PoivY which has some of the best rates around and calls are clear the ability to use multiple SIP providers means you are never going to get out of date with this app keep up the good work in CZ and I look forward to the next version. As I travel a lot my roaming bills could top 3,000 usd a month now I limit calls to WIFI and am sving 98% don't hesitate to buy this app I live in swizerland and plan a new VOIP venture soon in Europe I think I might be talking to the developers of this product soon
