On my phone (Samsung), it has differnt profiles (Normal, Silent, Driving, Meeting...), so if I set it to Driving, it has the voice mail "You've called SpaceCadet, I'm driving...", or if it is Meeting it is "You've called SpaceCadet, I'm in a meeting...". Same for texts, if someone texts me it sends an automatic preprogrammed reply. Maybe on your next upgrade see if you can get a phone that does the same - or even if your current phone does it. It took me a while to find the option and work out how to set it up. Once it is going though, it is a blessing. :)
