I have had my Evo for about 2 months now & can't believe that this hasn't happened yet; I got my 1st call while driving. I almost missed the call cuz the ringer in the bluetooth headset was fairly soft and didn't realize that the sound I was hearing was, in fact, the ringer.

I checked the settings and wasn't able to find a way to increase the ringer volume for bluetooth (BTW, the headset's volume control, doesn't seem to fix this issue). I looked in the settings list and couldn't find a way to change the bluetooth ring volume. IS there a way? and can I use my custom ringers thru bluetooth?
