My iPhone at various times does not ring when I have a caller but instead goes direct to voicemail. I have tried All of the suggestions previously listed and nothing works. Then after a period of time the phone begins ringing again with calls. This seems to be a problem with iOS 15.5 but it also might be related to my switch to XFINITY network. Is anyone having this problem with Verizon? Is this more common with XFINITY?If anyone has a solution which consistently works Please post it.
