Is there a Twilio competitor for which per-minute rates to Belarus aren't ~ $0.50 USD? I remember purchasing "calling cards" in the 90s at convenience stores with better rates.
I'm in a nearby (EU) country and the VOIP rates to terminate calls here are also quite expensive compared to Western EU countries. In a lot of cases it's actually cheaper to make calls to numbers here on a mobile phone from another EU country, than over VOIP.
Telephony in general is fairly cheap, so I'm guessing there's only one or two providers here providing VOIP termination, and without much competition they price their services as high as enterprise companies who need it will allow.
My home phone voip provider has calls to belarus at $0.25-$.30 (depends on destination), their terms don't allow automation though, so I won't link them. From what I recall of my time with automated voice calling, the voice api providers weren't too far above prices for my home phone, so I'm surprised there's a 20 cent premium.
