I upgraded one of our customers to UCM6.1.3 last night, and now have a small number of users that are complaining that they are hearing echo in their headsets. I suspect that this has been caused since the handset firmware was also upgraded and the gain control & side tone settings have been defaulted.
Please can someone advise as to where I would locate the parameters that control the headset transmit gain/attenuation, and the side tone level? I've had a look through the manuals and I can't seem to find it anywhere.
Thanks in advance for your assistance.
