Incoming call notification when I am already on a call

[nf]

When I am on a call and I receive a second incoming call or receiving a text there is a notification that the person I am on the phone with can hear....Is there anyway to get rid of that notification or limit it to my hearing only?  I use a DROID 2

Even with a landline people can tell when you have another call come in.

As far as the text, mine just vibrates when I'm on a call.

You should be able to set calls and texts to vibrate while on a call, but my wife has told me that she can hear that too.
