Calls and hangs up... busy when calling back.

Some dummy called, let it ring once and then hung up. We didn't even get a chance to answer. Lucky us.

Yes multiple times over past few days.  It rings once then hangs up.  There a pain

calls almost every day. no one ever there. so disruptive. obviously a robo call. I haven't tried to dial it back but it sounds like no one ever talks to anyone. They need to stop.

calls everyday. I am never here for their calls.
