Issue with 561 Headset

Hello,

 

Does anyone know if it is possible to downgrade the firmware on Cisco 561 headsets? I have a set of 561 headsets that were upgraded. Looking to downgrade because after the upgrade any calls for shared lines are beeping in the headset even though on the phone they are set to flash only.

 

Thanks.
