Apologies for my ignorance on this but
"Can a Cisco Router have 2 X interfaces to the same subnet"
Also, are there any helpful websites or resources on designing an IP Voice/Data Network?
Thankyou

From the perspective of the router itself, there is no problem with having two interfaces assigned on the same subnet. You could, for example, assign E1/0 to 192.168.0.254 and E1/1 to 192.168.0.253 and configure their behavior with static routes.
Where things will get interesting is when you configure routing protocols because you'll have to be very careful not to create routing loops.

I'm sure there are many Web resources out there for design of a VOIP network but I find the Cisco site is usually one of the best (although decidedly biased towards Cisco equipment.... of course!).
