I have my phone set to auto-deny any number that is not in my contact list to combat the ever increasing amount of spam I've been getting. Unfortunately there is one insurance scammer that has taken to leaving voicemails. Multiple VMs a day for the last two weeks.

I contacted my provider about disabling my VM box altogether. They do not support this. You can, however, redirect missed calls to another number instead.

I now send missed calls to: https://github.com/pjf/rickastley

Eat Rickroll, spammers!
