Heh. That sounds very familiar. In my IT department, about the same time, we wanted MFA on our admin accounts for services and generally SMS was the only way to do it. But how do you SMS MFA for a team of 5 or 10 people? Well, we used an android phone velcro'd to the wall running tasker and some custom server side scripts.

Even though we could have used Twilio, we chose to do it this way because a lot of services filtered for VOIP numbers and refused to setup MFA on them. So we needed a real honest-to-god number which was extremely annoying.
