> In those early years, we had one customer doing more minutes than our entire customer base. In fact, at an early Twiliocon (pre-Signal) John and Jeff had to help build out an entirely separate environment for them because it was dragging everyone else down.

As an early large customer, I wonder if that was me... sorry for messing up everyone else ;) I do remember some issues at times, but nothing we didn't see with other voice and SMS providers. Well, other providers didn't have an online log browser, so I never had trouble with browsing logs their logs.

Twiml was much easier to use than the other 'programatic voice' apis at the time, and I never had time to figure out how to run calls on sip directly. As I recall, it didn't take much time to setup voice calls, and then boom. It was helpful that quality was good and support was helpful when there were destinations with poor results.
