My phone rings once or not at all and all of my calls go directly to voicemail. I have tried everything I can think of in settings and can't resolve this issue. I am missing all of my calls because of this.
I can't figure out why my incoming calls are going directly to voicemail. Callers hear one ring and then voicemail and I don't hear it ring at all.
