Just called twice in the past hour. Blocked forever using my VOIPO

Keeps calling & leaves no messages. Caller shows name unknown.

Computer generated voice telemarketing. Always sounds the same when I say hello. Say they are installing wireless home security systems as intruders are cutting phone lines to the house first. Claim that crime is high in your area. Called from a different number yesterday. Cannot be validated as legit numbers.

I have received two (2) calls from the number above within 30 minutes apart.  Both times they didn't leave any messages.

Got a call from this number to my landline.  I don't have my vm on because most calls i get are bogus...
