CCM 4.1
Phone load SCCP41.8-3-3S
One site with multiple phones that will have the phone screens go blank during a call, drop the call and reboot. Some as many as 5-6 times in a few hours. Not all phones at this location are affected. There are only two switchports that show as being recently down. I am stumped about where to begin look for the root cause of the issue. Environment outputs from the switch stack looks healthy.
Thank you for your time!
