Same situation as Judith. Just hang up after I answer.

I have received several calls from this number within the last few days. I have always ended up missing the call, but next time I'm going to answer and see what's up. Hopefully they will not hang up on me.

calling and hangs up when I answer.  calls several times a day during work hours

I have got at least 10 calls from this number in the past 3 days and no one is there they just hang up its getting really annoying
