How to access the configuration files of the phone? #

One can download the phone's config file via TFTP from a PC command line (examples below.) The format of the filename to retrieve is usually devicename.cnf.xml, e.g.: IPCMRAEU5UCM5X7.cnf.xml

For example consider the following if one wants to get the config file for the phone IPCMRAEU5UCM5X7:

Linux: -------- root@bat31 # tftp 10.88.131.133 tftp> get IPCMRAEU5UCM5X7.cnf.xml

Windows: -------------- C:\Documents and Settings\ratray>tftp 10.88.131.133 GET IPCMRAEU5UCM5X7.cnf.xml Transfer successful: 5811 bytes in 1 second, 5811 bytes/s

The same information needed will be present in a pcap if one gets it from phone switch port from boot time onwards (avoiding this TFTP client business.)
