I have a BB Curve that chirps when I am in the middle of a call. It doesn't matter if I am using my handset, if it is on speakerphone, or if I am using my bluetooth. Verizon sent me a replacement phone and it is still doing it. Is anyone else having the same problems>
The problem you describe was found to be an error with the software on your phone. See the thread at http://community.vzw.com/t5/BlackBerry-Devices/High-pitched-sound-beep-while-on-calls-on-BB-Curve-83...
