Hello all: I'm currently running the latest version of asterisk, and using chan_bluetooth I am using the usb/bluetooth dongle from Compusa: http://www.compusa.com/products/product_info.asp?product_code=312330&pfp=SEARCH I am also using the M2500 Plantronics headset - 29.95 from Frys things are working great, I have audio in both directions, and some good range, now that I switched to the new usb dongle with the little antenna. However, all along, the microphone sensitivity of the headset when transmitted to the other end is very lound and picks up EVERYTHING, the dogs walking on the hard wood floor sound like a heard of elephants through the amazon! How do I tweak this audio sensitivity with this headset? And/or what headset would allow better background noise filtering? Thanks Ben
