Calling verbal Fair

[PABlue]

Game situation, with R1 and R2 less then two outs. I am PU, batter hits a line shot down left field ball lands directly on chalk line beyond third base, I signal fair ball but catcher, who is quite loud is yelling foul. I then signal fair again emphatically but also yelled out fair.
Proper in this situation or never do this again ever?

Keep pointing and consider verbal OBS on F2 (depending on the code and the situation).

Fed ball, it was a blowout game and the defense was on the losing side. Everyone kept play going with my fair call so I did not call for the verbal obstruction.
First time I yelled fair since my first year umpiring 30 years ago. I saw R@2 hesitate for one step between second and third when the catcher yelled I think that's why I yelled. Play developed smoothly from there with neither side gaining an advantage so I played on. BR got second and R1and R2 scored on the play cautioned catcher about yelling foul.
