Default Issue with caller volume, goes quiet with wind or noise around.

Hey guys,

Here's a description of the issue:
I'll be having a conversation on the phone and if there is a bit of wind or noise then the phone will drastically LOWER the volume of the caller. If anything I'd want the callers voice to go UP not down. Once I step out of the wind the callers voice will return to normal volume. It will literally go completely mute during these scenarios, very irritating! Same issue with noise suppression on or off. Is this some sort of "feature" I need to turn off? Why are my calls doing this?

Any help or input appreciated
