Our experience: We run BigCouch for Database and BrainTree for processing. We're using DTH Software for our rating engine at the moment. I don't believe any of these technologies have any failsafes built-in related to credit card processing (or overcharging), and so anyone who uses these systems has to perform their own sanity checks. It's extremely rare for billing to screw up in Telecom, because, essentially, that is the crux of all Telco business. Twilio is probably using a homegrown or Non-telecom billing system, but I don't have any insight into their operations. I would hazard a guess that it's homebrewed though as I can't imagine a processing company introducing an error like this (stranger things have happened). So yeah, I think this will be a one time incident, and frankly, their response was fantastic.
