So, I tried havinga Sprint Ip Relay op call the MCI ANI line (8004444444) and they apparently actually gave me the number for their line. If there's interest, I'll compile a list of these. Could be fun to (VoIP/Beige Box/Relay) a call to a relay op, i'll bet they'd be a bit surprised to have their own line ring. This could make for fun phone mobbing too.
