Cisco Unified Communications Manager Express (CME) Files

Cisco Unified Communications Manager Express is an IOS VoIP solution based on Cisco Integrated Services Routers. There are specific Cisco Unified CME files for each Cisco Unified CME IOS. A tar archive or zip file contains the files needed for Cisco Unified CME. Be sure to download the correct version for your hardware platform and IOS load. This tar archive or zip file typically contains the phone firmware files that you require. Check equipment and IOS compatibilities in "Cisco Unified Communication Manager Express 4.x Supported Firmware, Platforms, Memory, and Voice Products" found in the "Install and Upgrades" section of the Cisco Unified Communications Manager Express support pages at cisco.com.

The tar file does not need to be opened. The router will untar and copy the contents to the router flash maintaining the directory structure specified in the tar file.

Moving Cisco Unified CME Files to the Router Flash

Router# archive tar /xtract tftp:// ip-address/tar-filename flash:

Uncompresses and copies each file to router flash memory.

NOTE: Unzip the files to the TFTP server before copying to router flash.

Router# copy tftp://ip-address/filename flash:

Copies each file to router flash memory.

Router(config)# tftp-server flash:P0xxxxxxxxxx.bin

Permits TFTP access to the specified file by the IP phones.

NOTE: Each individual Cisco CME phone firmware file requires a separate tftp-server command.

SCCP firmware is designated by P003xxyy.bin and SIP firmware by P0S3xxyy.bin.
