My calls go to voicemail with Assistive Access
I have setup assistive access for my parents months ago and they love it. However recently when I call them, it immediately goes to voicemail like they have do not disturb turned on. Their phone rings when I call them a second time. I have gone through all the settings and nothing has changed. When I exit assistive access and re-enable it, their phone rings on the first call. This seems to only last for 24 hours before it goes directly to voicemail.
Is this a bug in the software? Has anyone else had this issue? Any ideas how to fix this?
