Iw? T?

Comments, please: Team A is out of timeouts nearing the end of a tie ballgame. They have possession of ball but get trapped on baseline, at their end of court. T (on bench side) thinks he hears A HC call a TO and hits whistle. Coach gives him a look of disbelief and says "I said 'get it out', not time out. I'm out of timeouts, why would I call one". What to do now? Give back to A under inadvertant whistle rule? Call T on A for excessive time outs?
