They are calling themselves to be a VoIP provider, but you can only connect with their own app to their service. They are saying that they are using "their own" SIP protocol, which is not compatible to the SIP standard. So be aware, to sign up with that provider, as you are only able to use their software and not any standard software. I did not sign up, after I have contacted the customer service who told me that. For this reason I'm not able to tell something if their service is working or not.

I have utilized this site for well over a year now. Except for concurred messages from Rebtel, I have had no spammy sort messages and there is no signs of utilization of security data for something besides account organization. The arrangements on the site are additionally great and consider modest global calls. This is a quickly developing site, so the data will be overhauled, I think, all the time, as more WOT clients run over it. Rebtel is second regarding client base, the VOIP market, just to Microsoft's Skype.
