Delay of Game??

[Rev.Ref63]

8th Grade Boys game. Team B commits a foul on A shooter. A's coach yells "huddle!" Immediately team A runs to sideline much like a 30 second T/O. Team B, thinking a T/O has been called, also runs to their bench. My partner and I looked at each other wondering if a T/O had been requested but neither of us granted one. I then reported the foul.
We immediately called both teams back to the game to shoot the free throws. In all, there was probably a 30 second delay. Was this the best way to handle the situation? Was there something more we could have done?
