ICON??? Blue and black rectangle with diagonal "+" dividing the rectangle

[BlackZwrx]

So I have never seen or maybe just never noticed this icon before. It shows on the screen when I am making a call( phone is ringing on the other end) and while I am talking to the person on the other end. It is in the top right corner of the screen. Its a rectangle with a line of 5 "+" signs going from the top left to the bottem right, of the rectangle. And the bottem half is blue, while the top half is black. Now that I think of it, I know I have never seen this icon before, because if a call was breaking up I would look on the phone screen at the top right corner to see how many "Bars" I had, only to realize that the reception meter moves to the bottem of the screen while "in call".
So Does anyone know what this Icon means? I tried looking it up in the BB reference guide, and it has all the other on-screen icon meanings, i.e. sending data, messages, voice mail, ect, ect. But no pic of this icon or meaning.
Any help here would be much appreciated, so thanks alot in advance

What Does This Icon Mean?

You mean this? It's the enhanced call audio. While on a call hit menu call audio. When set to Normal there is no icon.

Phone options > general options > enhance call audio. You must have either bass or treble boost activated, that is why you are seeing this mysterious icon. I personally don't think the feature really does anything that great. I've tried it and couldn't hear a difference. Anyway, hope this helps!

Thanks all very much!

I did try searching, but all that came up, well like 99% of the time was the app icons and how to move them.....

But thanks anyway, everyone has been very helpful
