IP telephony subscribers, or their children, can get updates as to Santa's whereabouts For little ones who simply have to know what Saint Nick is up to, Vonage Holdings Corp. has launched a free Santa Claus tracking service that can be used by its Internet telephony subscribers. Beginning Friday, Vonage customers — or their children — can get updates as to Santa’s whereabouts by pressing *101 from any Vonage line.As of Friday morning, Santa was preparing for the big trip, said Mitchell Slepian, a Vonage spokesman. “They’re loading the sled up and the reindeer are being fed with reindeer food,” he said.”They’re going to be going all over the world.”Over the past week, about 100,000 children have used Vonage to call Santa and leave messages on the same *101 line, Slepian said. Ten of those children, drawn at random, are actually going to get their Christmas wishes, compliments of the Internet telephone company, she said. That’s a respectable number of messages, given that Vonage has around 1 million subscribers in the U.S., Canada and the U.K., according to the company. The service is available to customers in the U.S. and Canada, Slepian said.For those still on the public switched telephone network, there’s always the venerable NORAD (North American Aerospace Defense Command) Santa tracker, which has now been in operation for 50 Christmases. Volunteers will answer calls about Santa’s whereabouts from 9 a.m. GMT Dec. 24 to 9 a.m. GMT Dec. 25 at 1-877-446-6723, which is a toll-free call in the United States.On the Web, NORAD’s Santa tracker Web site is already live at http://www.noradsanta.org/en/default.php Technology Industry
