This number keeps calling and hanging up after two or three rings. When you call back there is a generic message that says " Record your message and press #". No idea who it is, but it is becoming very annoying.

Got 2 missed call from this number. The caller didn't leave any message. Based on the existing comment, I would assume it's a spam.

They called me twice and hang up, very annoying

Spam, just block number

I missed the call but caller did not leave vm - so must be spam

They keep calling and hanging up after the first ring. suspect a spam dialer?

they just keep calling
