First, agree to Google's terms of service (even Santa has a legal team) and you are on the sleigh, er, way, to sending an adorable message to friends and family.
Answer a few questions via instant message to create the custom call and then Santa's elves prepare an MP3 for you to sample before sending the call on its way. If Santa can't pronounce your name, he'll call you by an alias. Options include Bro, Dude, Geek, Hipster and Hottie, among other choices. You can create some funny messages.
Besides calls, other options in the Google Santa Tracker include following Santa on Google+, downloading the Android App and tracking Santa's progress on Christmas Eve in 3D with the Google Earth App.
