it's not vonage, it's the voip offering from CIA.com (aka worst ISP to ever exist) but if you know how to get into the adapter without disconnecting my service that would be sweet, it's a linksys SPA2100 Phone Adapter i have all the instructions for logging into the thing and all, just don't have the user ID and password. i don't know if i have the SIP Proxy Address, the pamphlet says i need that too... anyways, thanks!
