What are the Verizon VoIP patents, anyway?

Here's a good question: what exactly are the patents that are causing all of Vonage's problems? Network World pored through the patent database and court transcripts and figured it out. One patent is about how VoIP systems do packet translation, changing domain names into PSTN phone numbers and back. A second is about supporting features like Caller ID and call waiting for VoIP customers. The third is about how calls can be moved from the Internet to a wireless network on a customer's premises.
