I have a user that has a Silver Plantronics CS55 wireless headset connected to the headset port on her 7941G. Callers to her are getting echo when she uses her headset.
I suspect that there is an amplifier in the headset base station that is causing this issue.
Does anyone know where I can find a list of BlueTooth headsets that have been tested with 79xx phones?
The Microphone input volume. It's a value on the bottom of the unit. That's the major value.
You can adjust the minor value with the +/- on the back next to the microphone image.
