This number shows the id "J2 Global Commu" but consistently hangs up. I don't believe that it is this company. There are other reports of other numbers with this id, which appear to be solicitations/telemarketers.
set up a new contact on your phone called "no answer" ... then block all calls from that contact. Each time you get a call from a number you do not want to ever get again, just add them to that contact.
