I have recently installed a CS600 with 120 Local IP phones. They are connected to new PoE switches. Customer has Plantronics CS70 headsets with handset lifters. There is alot of sidetone while communicating. Have tried adjusting transmit levels on the CS70 with no luck. Does anyone have a suggestion for a differnt headset? Or has anyone else experienced this?
Also when you turn the handset volume down to reduce sidetone you can't hardly hear the caller.
