The weirdest thing just happened. I was doing the dishes with radio on and in the back round I'm hearing someone saying hello, hello. I thought I was going crazy. I turned down the radio and I here it coming from my phone.Sure enough it was my girlfriend and she was talking to me. The phone didn't ring and she said she called twice and heard my radio on and called back. The question is,how did the phone connect without me accepting the phone call?
