Has called our business several times and immediately hangs up. Likely a mass autodialer, they call several numbers at once, when someone answers it drops the remaining calls and transfers the one that answered to a telemarketer.  Number now blocked, problem solved.

I forgot to block this #, it called back a few more times and I did talk to someone. The person claimed to be on official representative calling for centurylink who wished to speak with the owner about our phone services.  This is most likely not true, they would in fact know the names on our account. Now I did block this number.

left no message, caller id says centurylink.

Called me today, did not respond when I answered the phone.  Caller id says Century Link.

Spoke to them and they said they are an authorized representative calling on behalf of Century link and our account is elegiable for special promotions and pricing.  hung up as I always do.
