How do you bypass having a persons phone ring, so it goes straight to
the voicemail from someone who uses Verizon?  I would
like to leave a message without having their phone ring or know I
called. If it not possible then that is not an answer.  I am looking
for only something possible.

A similar question that answers T-Mobile is found here in link below. 
Even though he was looking for a different answer, I am looking for an
answer similar to the first response with the 805 number and not a
simple "press 1 after you hear tone" thing. Thanks!
