Counterparty was a family member, also on the phone line, and who provided their permission to both Schwab and their bank to do it. My point still stands. It was highly unconventional and Schwab didn't have to do it, but they did in order to help me out. I'm sure it's not standard practice, and I wouldn't count on another banker doing the same, though Schwab has a knack for being customer-friendly.
