My iPhone calls go to voicemail on another iPhone
One number; right to voice message. When I call only one other iPhone, it goes right to voicemail, but not when anyone else calls that number. That number can call my iPhone, and others, just fine. I have an SE Gen 2 and the trouble phone is a 17 Pro (I think; 17 something). We have looked at settings on each phone; nothing. Both my phone and the trouble phone have been updated recently. Any clues? Thank you. john
