1. Can you provide a much better explanation of what "routing [a] NVG510 to a phone module" entails?
2. What will this do for you?
3. What connections are you using on the NVG 510?
4. When "the router fails," what does that look like (error messages, lights, etc.)?

@MSECPDEP1, as my thoughts indicated, the correct device for connecting multiple Ethernet connections together is a Switch (or a hub, though hubs are pretty much obsolete these days).  You cannot treat cabling used for twisted pair Ethernet the same way you would cabling for analog telephones; that will not work at all.  Twisted-Pair Ethernet cabling uses point-to-point or star topology, not a bus like 10base5 or 10base2, which use Coax as a shared medium and  carrier sense multiple access with collision detection (CSMA/CD) to prevent nodes talking over each other.  Only two nodes are ever on a Twisted-Pair Ethernet cable; one on each end.

Look for Gigabit Ethernet Switch on Amazon or wherever you like to buy electronics.  The Netgear GS105 or GS108 are often used by AT&T when needed for this application.

I thought that you might have been attempting to connect multiple phones to the VOIP jack on the NVG510.  That is possible.

Thanks for your help.  I will be getting switch today. I was trying to use a Leviton Bridged expansion board.
