iPhone Goes Straight to Voicemail (sometimes displays “User Busy”)
I am very knowledgeable about my Apple products. For the past year my iPhone 11 was going straight to VM with no manual intervention (Airplane Mode, Focus, silent, etc.). It is now happening with my iPhone 13. This has happened randomly, and for no apparent reason. I have researched various articles and posts. In almost every post it goes thru the steps I mentioned above. I have done that several times. I’ve checked and there are no carrier updates. My watch settings are not set to “mirror my iPhone”. I’ve tried Wi-Fi calling turned on and off, that didn’t fix it. Battery health is at 99%. Phone set to Announce Calls. Silence Unknown Callers is off. In a couple of instances when the call comes in it is displayed on the screen and says “User Busy”. When that happened I turned “Call Forwarding” off, which fixed it, however I never set it to forward calls. I spent two hours on the phone with an Apple Senior Advisor, they were unable to determine the problem. I did screen recordings of the settings while they were on the phone which I sent them, along with my other documentation.
Sometimes resetting the network settings has fixed it, but not always; turning AP mode on and off fixed it a couple of times, changing my watch settings to Custom, not Mirror my iPhone, fixed it once, I’ve completely reset my phone twice which never fixed it. When it happens I just start changing settings, re-booting the phone, etc., and it is eventually fixed…until the next time.
I see lots of articles on this, some old, some this year, which makes me believe this is not unique to my iPhone or carrier.
I’m hoping someone has the miracle fix I’m looking for. This is extremely frustrating, and when it happens I don’t know it until I see a missed call or someone texts me.
