That's fair - I've found the opposite: all this does is effectively push up the voicemail service to a layer I can interact with (as opposed to google voice voicemail) and usually important calls will attempt to interract with the robo screener or leave a message whereas spam will just ignore the robo screener entirely. This is purely my personal experience though and depending on how you use your phone (like in a business setting) and with who (like people who are legitimately busy) you may experience the complete opposite experience.
