Ty for the replies.

Speaker volume is not the issue...when speaking on my bluetooth via Blackjack, I get reports from call recipients that it seems that I'm yelling at them.

I've been aware of this for some weeks, and make a point to speak at normal levels (actually, I've even spoken at below normal levels) and ask for a quality rating on the call and volume. Call quality regularly registers well, but the complaint still exists that some people have to pull the phone away from their ear from time to time. This has been with both land and cell phones, and with different recipients.

** I could have sworn I saw somewhere a list or pdf of all the dealer customizeable settings, but for the life of me I can't remember where it is.
