Amcrest AD410 / Dahua Doorbell Button not working

Hello,
The doorbell button on my Amcrest AD410 doorbell camera button has stoped working? If I reboot the camera it will work once, It seems to be getting stuck in a call or something as the button remains armed…?

I have seen some forums mentioning a back channel 0 change to address this issue

forum post link mentioned above: Ad410, does not ring mechanical chime - Page 3 - Amcrest Forum

I am usure how to make this change as I dont use frigate I use the Dahua HACS addon. Please help!
