Calling from the circle

[emaxos]

Local FP Dixie rec league had opening day Saturday which included some unofficial games. All games had one man crews. I saw one blue calling the game from inside the circle. Never saw that before in about eight years. Seemed to be a bit distracting for the pitcher.
A spectator commented that the same blue had called a Fed game from the circle recently until his partner showed up. Claimed he didn't have his equipment with him. He stayed in the circle through 4 different games Saturday. My guess is perhaps he doesn't have any protective equipment. League President told me he wouldn't allow it for an official game.
Can a Fed game be legally called from the circle? Any org allow it in FP?
