For those pesky calls that I send straight to VM ...

How about an option for the caller to hear X number of rings first?
My preference would be 6 rings as one option, 0 rings as another.
(I do not want to hear the rings, just let the caller hear them.)

The idea is, making the call more of a nuisance, for the unknown caller.

It should be easy, as it would just prepend to the outgoing message.
