No foul is the correct call. You were right in deciding that since you did not see how it came out, you must assume that it came out in the course of play.

However, please do not yell at a coach from across the field to "stop talking". Is that how you would like to be treated if you were coaching? Send the info over with the wingman. If you are working 3 man without a wingman on that side, then get the info to him yourself or by the R. If a coach is a continual whiner, you might at some point have to hold up your hand and say "That's enough coach", but try to avoid doing that from across the field. Nobody likes to be shown up in front of their players and fans.
