The article explains:
Kelly informed Sanford police of the situation. Upon arrival at the family's home, officers confronted a rather confused and embarrassed father who admitted his son had been playing with his cell phone.
They had moved, the father said, and had not bothered to update their phone carrier, Vonage, with their new address.
What I don't get is how the baby dialed 911 using a cell phone that is tied to Vonage's service. Since when did Vonage start offering cell phone service? If 911 was dialed from a cell phone, the tracing of the call should be performed from the wireless carrier not Vonage.
The only thing I can think of is that the father installed some sort of Vonage software on his mobile phone that enables outbound calling through the Vonage service. But if such a piece of software exists, I'm unaware of its existence. The closest thing is Vonage Companion, and that is designed to run on PCs not a mobile phone. I'm more confused over this than the mainstream media was over the Governor Sarah Palin VP pick.
