Just had this issue come up. When I go to make calls, it never rings. It will eventually cancel the call. Also, when people try to call me, they say it will either ring and never reach my voicemail or they will instantly get my voicemail. This does not occur on all calls. I have good/great service, have done a reset, checked my SIM card, checked airplane mode, etc. Nothing seems to resolve the issue. Anybody else dealing with this or know how to resolve it?
