I have a small network with about 10 Cisco 7900 phones being run by a Cisco UC520 16user Router (info here). I am looking to move to a Hosted VOIP solution and would like to reuse my 7900 Series phones with the hosted voip provider. How can I go about disabling callmanager express and unity express from within the UC520 router so that It only functions as a data router?
Is this a simple configuration change? Or will I need to replace the router with a standard data router?
