We are getting ready to setup a test environment for our phone system (CCM 4.1.3 with IPCC 4.1). What I need to know is do I need to set this up completly isolated from the production environment or would I be able to use the current architecture? Basically I finished getting the new CCM and IPCC servers setup but I don't have any extra switches to plug the phones into so I'm just trying to figure out if I can use our existing switches or if I am going to have to get another switch for the test environment. If anyone has any links to setting up test environments I would be more than happy to take a look, I cannot seem to find hardly anything regarding that on Cisco's site. any other suggestions or ideas are also welcome.
