Hello,
On Saturday, my doctor's office was trying to call me. It would ring on my end. I would answer and see the call timer start. It would get to 00:01 and then went straight to 'Call Ended.' I tried calling from our landline and I got through. My husband called and it got through. The doctor's office called and the same thing happened with the call being ended. They said they hear it ring twice and then goes to silence. It doesn't even allow them to leave a voice mail. I tried from my work line and I got through just fine. I've restarted my phone and reset the network settings. What can be the issue????
