Twice my phone has gone into a weird mode. The icon next to my name changes to and X and in the corner where the date appears it flashes a triangle with an ! I still have a dial tone but my calls go directly to voicemail. And I haven’t been pressing anything on my phone. To fix it I just unplug and then replug my phone but my concern is that I don’t notice when it happens and I may end up missing calls. Not finding anything like this in the manual or on Google. Any help would be greatly appreciated.
Thanks so much!
