Thanks for your Help, but nothing does help. So i erased all Content and Settings, i also installed iOS9 again, but nothing helps. The Call Audio Routing is configured to Automatic. I have no Bluetooth Devices connected to my iPhone, because in my Car is a Phone in the Audi MMI System integrated and i dont like Headsets.After trying your Tipps i reproduced the Problem without a Problem. I called myself over the fixed network 5 times the iPhone was ringing, after the 5th try it wont work until the 10th try, then it rings again.Maybe it is a Bug or a Feature?Sometimes it seems like that it is a Feature, if someone calls you again and again (maybe 5 times in one minute) and you do not answer, then it is like a Mute Function for 1 or 2 Minutes until it rings again. But i dont think, that it is a Feature, because the People who called me in the last Days where i experienced the Problem called me 5 -10 Minutes before the Problem happens.So sorry for my bad English.
