If I were to open the ports needed for a skinny protocol phone to connect to the CME how can I prevent unauthorized phones from logging in and being assigned an extension? I am not worried about encrypting the data but would like to have some type of authentication involved.
Not necessarily our system has autodiscovered all phones connected the the local LAN. I am guessing via CDP or something. My hope is that whatever technique is used to autoconfigure local LAN phones is not available via WAN.
