We have got Cisco-520 along with 16 user license and we are going implement IP telephony in our environment for the first time.
I have few pre-implementation questions
1. I saw in the specification that this model supports all latest models of Cisco IP phones and most of the settings are pre-configured to support for small businesses. So in this case When I connect an IP phone to the router's PoE port will the phone auto-register and get its firmware and the configuration?
or do I need to specify the phone loads for each model ?
2. In case If I need to load the firmware and settings manually in CME what steps I need to perform? will I be able to do it from CCA ?
also suggest me any other steps to connect my IP Phones and make them work with their internal extensions (I have already created internal dial peers )
