Hey guys! I'm looking into making my own VoIP phone number service similar to Twilio. I've looked all over the internet for this, but wasn't able to find anything about creating **valid VoIP phone numbers that anybody is able to call from their phone**. What I mean by this is numbers like (929) xxx xxxx. ​ I would appreciate any insight on how to host this :) Before anybody recommends it, NO, I do NOT want to use any third parties like TextNow or voip.ms.
