Installing the Cisco Unified CME Router
First make sure you have installed your router an IOS suitable for CME.
The CME software includes a set of files, divided into the following categories.
Basic files: These are the core files that are required to operate the CME. These files also include firmware that allows Cisco IP phones to operate.
Gui files: These files make it possible to control the CME web.
XML template files: These files determine the control structure of Web pages for the configuration of the CME.
Changing these files allow you to create different levels of administration.
- MOH files: audio files are used for Music on Hold (MOH)
- Script files: Defined as Various Tool Command Language (Tcl) script files to provide advanced functions in the CME (eg automatic call distributor ACD)
- Miscellaneous files: There are additional files that allow you to customize the ring tones or background different models Cisco IP Phones

TIME
Setting the Clock of a Cisco Device with NTP
CME_Voice # configure terminal
CME_Voice (config) # clock timezone EN 1
CME_Voice (config) # clock summer-time IT Tues recurring last Sun Oct 2:00 last Sun 2:00
1) Installing CME Files Into Flash Memory
CME_Voice # archive tar / Xtract tftp: / / 172.16.10.1/cme-full-4.3.0.0.tar flash:
For the full installation of software package in the CME router is unpacking the tar file from tftp to flash the router.
2) Configuring Router-Based Services for IP Phone TFTP Firmware Files
CME_Voice # configure terminal
Enter configuration commands, one for line. End with CNTL / Z.
CME_Voice (config) # tftp-server flash: / alias phone/7940-7960/P00308000500.bin P00308000500.bin
CME_Voice (config) # the tftp-server flash: / alias phone/7940-7960/P00308000500.loads P00308000500.loads
CME_Voice (config) # tftp-server flash: / alias phone/7940-7960/P00308000500.sb2 P00308000500.sb2
CME_Voice (config) # tftp-server flash: / alias phone/7940-7960/P00308000500.sbn P00308000500.sbn
The following commands are used to configure the firmware for the phones, in this case a 7940 and 7960.
Alias syntax that follows the tftp-server command lets you create a label, thus avoiding to rewrite the whole path, as the CME organizes the firmware in subdirectory.
3) Configuring the Cisco Unified CME System-Level Functions
Now install the four key system-level functions or that the CME Router acconsetono starting to support Cisco IP phones.
-Maximum phones and directory numbers
-Firmware load files
-Source IP address information
-Generated configuration files
3.1) Before the CME router to register and support phones, needs to know the telephone number and directory number that must support.
To configure the 4-key system must enter the telephony-service command from global configuration mode.
CME Provisioning and Directory Number Phone Support
CME_Voice (config) # telephony-service CME_Voice (config-telephony) # max-ephones? <1-30> Maximum phones to support CME_Voice (config-telephony) # max-ephones CME_Voice 24 (config-telephony) # max-dn? <1-150> the Maximum directory numbers supported
3.2) The command max-ephones? I can see how many IP phones supported by routers, while the max-dn command the maximum number of directories that can be created.
Continue configuring the IP phone firmware:
Configuring CME for 7970 and 7971 Firmware Loads
CME_Voice (config) # tftp-server flash: / alias phone/7970-7971/apps70.8-3-2-27.sbn apps70.8-3-2-27.sbn
CME_Voice (config) # tftp-server flash: / alias phone/7970-7971/cnu70.8-3-2-27.sbn cnu70.8-3-2-27.sbn

CME_Voice (config) # tftp-server flash: / alias phone/7970-7971/dsp70.8-3-2-27.sbn dsp70.8-3-2-27.sbn
CME_Voice (config) # tftp-server flash: / alias phone/7970-7971/jar70sccp.8-3-2-27.sbn jar70sccp.8-3-2-27.sbn
CME_Voice (config) # tftp-server flash: / alias phone/7970-7971/SCCP70.8-3-3S.loads SCCP70.8-3-3S.loads

CME_Voice (config) # tftp-server flash: / alias phone/7970-7971/term71.default.loads term71.default.loads

3.3) IP Address Source Information
CME_Voice (config) # telephony-service
CME_Voice (config-telephony) # ip source-address 172.16.10.1
Ip source-address identifies the IP address by which the phones can communicate with the CME router, typically the address is the ethernet port on the router.
3.4) As a final point, we must now create the configuration files for Cisco IP Phones.
Once the IP phone gets an IP address and information from the TFTP server from DHCP, waits to contact the TFTP server to download configuration files and firmware. IP Phones uses the configuration file to determine which IP address to use to contact the CME router, you can download the firmware, the number of IP Phones and other configurations.
If you want to manually instruct the router to create the configuration file, use the commands below:
Generating IP Phone Configuration Files
CME_Voice (config-telephony) # create cnf-files
