All my calls, regardless of who they're from, go straight to voicemail. I do not have any contacts that I have checked to send straight to voicemail. Nor do I have any 3rd party calling apps. The only thing that I've done recently is do the software upgrade to system version 21.44.8.en.US.
I turned the phone off and on, and had 1 contact call me and it works. Is anyone else having this issue? Is it ongoing?
