The above number called my landline and since I didn't recognize the number, I let my answering machine pick up...I heard voices in background, but no message was left on my answering machine.  I tried looking up that # online to see if it was a spammer but couldn't find anything, so I decided to call the number back. A voicemail message said "the mailbox is full, no message will be recorded".  Probably spammers.
