Somewhat off-topic, but what wholesale SIP provider would you recommend? Looking for something small-scale for now, pay as you go as opposed to $X,000/month.
Twilio, voip.ms, or DIDlogic. Twilio may be for large users, but it works great for tiny ones as well. No minimums, simple wholesale pricing, and they still have free support even if you don't want to spend thousands a month for 24/7/365 phone support with an expert.
