[AC Question]

When I answer a call, it is rejected automatically, even when I press the green answer button. I'm using an Nexus 4 rooted phone with Cyanogenmod ROM. I've had this rom for a long time but only had this problem for a couple of weeks.

I think it has something to do with call forwarding or other related settings.

Does somebody know how to resolve this or maybe how to set all these settings back to default?

Thank you in advance.

Due the too many problems missing calls I had to do the drastic solution for me, which was to do a factory reset, just so if someone else has this problem, they know there is some kind of a solution.
