Your configuration seems to be wrong. It is to be connected in the different order:
Cable Modem <--> Linksys Router <--> Vonage VOIP
<--> Laptop
So both laptop and Vonage are to be connected to router. Router is to be connected to Cable Modem and configured to work as DHCP server so laptop will receive IP address from it. Vonage VOIP should has a static IP address not conflicting with DHCP. Router should be configured to forward UDP ports to Vonage VOIP box.

Let's say Router IP is 192.168.100.1 and DHCP server on it will assign addresses from 192.168.100.100-192.168.100.254
Vonage VOIP will have address 192.168.100.2
Router will forward relevant UDP ports to Vonage VOIP (http://www.vonage.com/support.php?article=1098)

Hope it will help.

igor, if you are corect, then he will have to call/beg/plead with his ISP to release the cache.

Cloning MAC is only good if ISP limiting the number of the connected devices (which is quite obsolete considering that most of the routers are able to clone MACs). Regardless of this, Router is to be the first device connected to the Cable Modem. All other devices are to be connected to the Router which is to be properly configured to allow port forwarding (in case if its FW is enabled). It's how I have it set in my household.

My ISP still does this and they have a large customer base(1mill+). YOu may call it old and antiquated but still valid plus, many ISPs do not suport 3rd party routers.

Well, it is enough to set the router WAN port to clone MAC address of the device the cable modem is locked to.

FOr now, he has accepted my solution. I guess we will have to wait for them to repost if it is incorrect.

Sure.
