Recently when I receive a call on my iPhone 7 the call goes directly to my voicemail box without ringing, and btw I don't have my voicemail set up.
I've just started fooling with the call and text features of the phone and my mom is my only contact.
I recently tried to change the ring tone and text tone and I believe that that's when this all started because before that I'd occasionally receive calls, presumably from robo calls, and the phone would ring then although I wouldn't answer. I first changed the tones just in contacts under my mom's contact because I didn't realize at the time that I could also change it under settings. I went into settings late last week though and found that I could change tones there as well, so I changed them there and then went under my mom's contact and changed the same tones I had set in settings. I think that's actually when the phone stopped ringing, then somebody told me to turn the phone off and back on so I did that and the phone did start working normally for a day or 2 after that, but my mom tried to call me over the weekend and again the call went straight to voicemail instead of the phone ringing on my end. Btw I'm receiving texts with no problems.
Oh and I just checked and my ring tone in settings is set to seaside and the tone under my mom's name in contact is set to I think open, so that might be the problem but I thought different tones can be set for different people so maybe not.
Sorry for this note being so long but I needed to write all I've done and tried, does anybody have any ideas what might be wrong and why my phone isn't ringing?
