I did have to forward UDP ports 5060 and 5061 to the Vonage box.

I believe you can either buy one directly from Vonage, or you can go to 
most electronics stores and buy one there. But you will need to buy the ATA.

I'm using the Linksys PAP2 ATA, and it can do DHCP or static IP. I left 
mine as DHCP and assign a static IP through the DHCP server.

I haven't experienced this myself, but you'll experience breakups in 
conversations from latency and jitter. One project I've been meaning to 
start is setting up QoS on my linux router.
