Files from tftp server
Reading through the cisco ccna voice book, not long started it. With regards to the IP phone boot process, when the phone downloads the initial configuration file from the tftp server (cnf.xml), are these the files we download from the Cisco site and then transfer to the tftp server? Just that the book states the filenames for each phone are SEPmacaddress of phone, so I'm wondering how the tftp server already has the Mac address of the phone and a specific config file for each when in reality this could be the first time the IP phone has contacted the tftp server? Someone else explain where I might be going wrong with this?
