Internal VoIP Network

I'm finally back from traveling and had some downtime to begin studying once again. I was able to finish setting up my internal VoIP network and I can place calls between both phones now. The configurations for the phone settings is done through the router CME using ephone commands. I assigned one phone extension 1001 and the other 2002. Once I get a little further in my studying I'm going to configure the T1 connections between my two 1760's to simulate placing calls to a remote site over a WAN link. I'm planning on taking the CCNA:Voice test before the end of the year so I can begin ramping up for the CCVP a little after April once I'm in my new place.
