100X the price? When it comes to SIP trunking at least, Twilio is one of the cheapest[0] if not the cheapest pay per minute provider. Compare with Flowroute[1] for instance, another popular SIP trunking provider, Twilio is significantly cheaper, especially on origination.
Twilio is good at one thing. And that is the developer experience.
If you are willing to pay 100X the price, in order to have awesome documentation, then Twilio is the right solution for you.
Otherwise.... Well.... Anything else is probably better.
