I've signed up for it and then asked about pricing. They told me they can't do anything on pricing and couldn't beat my current provider. The lower prices are for resellers and wholesalers only apparently. And I believe someone pointed it out earlier that they shouldn't offering lower prices since we aren't resellers but are end users. Also I asked why they couldn't beat my current prices, the reply I received was that my current providers and other providers like Voip.ms or Twilio don't have the network and support they have.
I've tried the system, I've had failed calls outgoing and then I get these charges for CID lookup and these other charges other providers do not charge. All the reviews on google look consistent so I'm not sure if a customer actually wrote them or the employees. Also I couldn't find out about their history either. No history, no reviews, sketchy pricing = I'll take my business elsewhere.
