Who called from 5878812001

Rang, I picked up. Said Hello, several times. No sound on other end. Then the line hung up.  Caller ID just said Alberta. Likely a telemarketer.

Same thing happened just now to me, but on my business line at home.

I said hello several times, finally a woman knew my name, but then the line went quiet and I hung up. When she asked if I was who I was, I thought afterwards this could be one of the scam calls trying to get me to say 'yes'. I hope this isn't the case and that I won't have trouble but I wouldn't answer this number again

NO one has this land line number so i know its not a call ive invited ..... so i answer but do not reply ..... voice on the other end says to someone else " dont you hate it when that happens"   then they hang up

Same thing.   Block the number.
