Who called from 5400763942

Got a call that displayed this bogus number on the caller ID. Female voice asked to speak to my husband. I offered to take a message and the caller just hung up.

Female voice asked to speak to "Dan" and when I asked who was calling she hung up... also a bogus phone number that cannot be called back.

SamE as above, called for my husband and when I asked who was calling said
Tell him I called and hung up.  I see on my caller Id they have called a couple more times...  Called back and it is just a busy signal.
