Hello everyone.

Here is list of my equipment, not much but its enough. I want to use it for my home network too but not sure if it will work out.

Cisco 2620 XM router (Single Ethernet Interface) with 4FXO vic and POTS line
Cisco 2650 switch
7950 IP Phone
Comcast Cable

Would I be able to use 2620xm with a single Ethernet port for my home network ? Is there another Ethernet module I could buy, since Comcast would be on 1 interface and my switch on another interface. Or should I just buy a 2611xm with 2 ethernet ports. Also, In the future I would like to also use the router for VOIP but I have no idea what IOS would I need to support CME and VOIP on this router. Also, not sure how to configure 4fxo port to route calls to.

Any advice is appreciated.
