Om Malik has a great post today about prior art for the VoIP patents.   There is also a good Wiki site scratchpad summarizing the claims.   One of the papers identified by Om was published on January 13, 1997, describes the process of using a gateway server to translate a VoIP call into a number to be used to access a telephone network.  This is the same process described in Claim 26 of Patent ‘574.

The Vonage legal team needs to make a public call for prior art documentation.  Keeping their search for prior art under wraps may result in a failure to find clear prior art evidence.
