7970 Phone SIP 8.5.3 Firmware Missed Calls Blink forevor

I’ve got a 7970 phone succesfully connected to Asterisk.

When missed calls come in, there seems to be no way to clear the calls other than reboot the phone.

This leads to constant blinking of each line’s orange light until you reboot the phone.

Even going in to missed calls and clearing history does not work - the calls never get cleared from the history even if you hit the clear button.

Has anyone solved this issue?
