How To Install Cisco Call Manager Express CME Software

Installation of CME software
After you download the .zip CME software file from Cisco, uncompress the file on a local TFTP server. You will get several individual files and several TAR archives. We assume the TFTP server is at 192.168.10.1 and has access to the CallManager router.
For individual files:
Use the regular copy command to transfer the file from TFTP to the router’s flash:
Example:
Router# copy tftp://192.168.10.1/P00307020300.sbn flash:
For TAR archive files:
Use the archive command to transfer the files and extract them at the same time to the router’s flash:
Example:
To transfer the Basic Files tar archive (cme-basic-3.0.3.tar) to callmanager router:
Router# archive tar /xtract tftp://192.168.10.1/cme-basic-3.0.3.tar flash:
After all required files are installed, use the “show flash” command to list the files installed on flash memory.
