Note: Use the Command Lookup Tool (registered customers only) to obtain more information on the commands used in this section.

CallManager Express 3.2.1

Complete these configuration steps for CallManager Express 3.2.1:

Ensure that you place these specific Cisco 7970 IP Phone files into the Cisco CallManager Express Flash:
```
cnu70.62-0-1-6.sbn
jvm70.602ES1R6.sbn
TERM70.DEFAULT.loads
TERM70.6-0-2SR1-0-5s.loads
Jar70.2-8-0-104.sbn
```
Note: In order to obtain these files, you must download the cme-123-11XL.zip file from the Voice Software Download (registered customers only) section of the Software Center under Voice Applications > Cisco CallManager Express/Cisco IOS Telephony Services and SRS Telephony. The Cisco 7970 IP Phone files are compressed in the 7970-602sr1-5.tar file.

Issue the show flash command in order to verify that these files are placed on the Flash:
```
CME3.2.1#show flash:

1  16219864  c1700-ipvoice-mz.123-11.XL.bin
2  1796886  cnu70.62-0-1-6.sbn
3   988400   jvm70.602ES1R6.sbn
4   612      TERM70.DEFAULT.loads
5   616      TERM70.6-0-2SR1-0-5s.loads
6   713081   Jar70.2-8-0-104.sbn
```

Configure these CLIs so that the Cisco 7970 IP Phone can download those files:

CME3.2.1#configure terminal

        CME3.2.1#tftp-server flash:cnu70.62-0-1-6.sbn
        CME3.2.1#tftp-server flash:jvm70.602ES1R6.sbn          
        CME3.2.1#tftp-server flash:TERM70.DEFAULT.loads          
        CME3.2.1#tftp-server flash:TERM70.6-0-2SR1-0-5s.loads          
        CME3.2.1#tftp-server flash:Jar70.2-8-0-104.sbn

Ensure that you configure the appropriate load for the Cisco 7970 IP Phone under Telephony-service:

CME3.2.1#configure terminal
CME3.2.1(config)#telephony-service
CME3.2.1(config-telephony)#load 7970 TERM70.6-0-2SR1-0-5s

The clocks in the Cisco 7970 IP Phone units obtain Greenwich Mean Time (GMT) from the clocks of the Cisco CallManager Express router. In order to display the correct local time, nearly all the time of the Cisco 7970 IP Phone 7970 units must be offset with the time-zone command.

CME3.2.1#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
CME3.2.1(config)#telephony-service
CME3.2.1(config-telephony)#time-zone 5  

!--- 5 for Pacific Standard/Daylight Time -480.

CME3.2.1(config-telephony)#end

Note: Ensure that the Cisco CallManager Express router receives the clock from an Network Time Protocol (NTP) server:

CME3.2.1#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
CME3.2.1(config)#ntp server 129.7.1.66
CME3.2.1(config)#end

Issue the show clock and show ntp commands in order to verify that the Cisco CallManager Express router is synched with an NTP server and has the correct time:

CME3.2.1#show ntp status
Clock is unsynchronized, stratum 16, no reference clock
nominal freq is 250.0000 Hz, actual freq is 249.9989 Hz, precision is 2**16
reference time is C546AEE8.4A0E878B (21:17:28.289 PST Wed Nov 17 2004)
clock offset is 1.6617 msec, root delay is 54.09 msec
root dispersion is 3880.97 msec, peer dispersion is 3879.30 msec

CME3.2.1#show clock

15:33:18.214 PST Thu Nov 18 2004

Note: In order for changes to the time-zone setting to take effect, you must update the Sep*.conf.xml file by issuing a no create cnf-files and then create cnf-files command. Also, you must reboot the Cisco 7970 IP Phone units with the reset command.

In order for Cisco CallManager Express to create the Sep*.conf.xml, the CLI "type 7970" must be configured under the ephone. For example:
```
ephone  1 
mac-address 0011.2032.C999
type 7970
button  1:1 2:2 3o23,24 4:27
```
It is then crucial that you issue these commands:
```
CCM3.2.1#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
CCM3.2.1(config)#tele
CCM3.2.1(config)#telephony-service

CCM3.2.1(config-telephony)#create cnf-files
CNF file creation is already On
Updating CNF files
CNF files update complete
CCM3.2.1(config-telephony)#end
```
This forces the Cisco CallManager Express router to create a config file with the MAC address 0011.2032.C999 that is specific for the Cisco 7970 IP Phone. Without this CLI (load 7970), Cisco CallManager Express does not create a SEP00112032c999.cnf.xml. This .xml file is needed so that the Cisco 7970 IP Phone can function properly (which includes the correct clock).

CallManager Express 4.0

Complete these configuration steps for CallManager Express 4.0:

If you are running CallManager Express 4.0, make sure that these 7970 IP Phone files are placed in the flash:

CME4.0#show flash

System CompactFlash directory:
File  Length   Name/status
  1   31441504  c3825-ipvoicek9-mz.124-9.T.bin
  2   1994898  CVM70.2-0-2-26.sbn
  3   866919   Jar70.2-9-2-26.sbn
  4   591      TERM70.7-0-3-0S.loads
  5   1979692  cnu70.2-7-6-26.sbn
  6   591      term70.default.loads
  7   591      term71.default.loads

Note: The phone firmware filenames for each phone type and Cisco CME version are listed in the appropriate Cisco CME Supported Firmware, Platforms, Memory, and Voice Products document.

Enable TFTP file sharing for new phone firmware files.

CME4.0#conf t
Enter configuration commands, one per line.  End with CNTL/Z.

CME4.0(config)#tftp-server flash:CVM70.2-0-2-26.sbn
CME4.0(config)#tftp-server flash:Jar70.2-9-2-26.sbn
CME4.0(config)#tftp-server flash:TERM70.7-0-3-0S.loads
CME4.0(config)#tftp-server flash:cnu70.2-7-6-26.sbn
CME4.0(config)#tftp-server flash:term70.default.loads

Associate the phone type with a phone firmware file and reboot the phone.

CME4.0(config)#telephony-service
CME4.0(config-telephony)#load 7970 TERM70.7-0-3-0S
 
!--- When configuring the load command, do not include !--- the .sbin or .loads file extension

CME4.0(config-telephony)#create cnf-files

In order to verify which phone firmware is installed on a particular ephone, issue the show ephone phone-load command.

CME4.0#show ephone phone-load


DeviceName        CurrentPhoneload       PreviousPhoneload           LastReset

Troubleshoot

How to Troubleshoot a Cisco CME System

In order to troubleshoot the Cisco CallManager Express system, perform these tasks:

Issue the show ephone command in order to display all registered phones. If no phones are registered, then perform these steps:
1. Check the DHCP configuration, including the default router and the TFTP server address (option 150).
2. Issue the dir command in order to check that the required files are in the router Flash memory.
3. Check that the tftp-server command is set for the required files.
4. Issue the debug ephone register mac-address command in order to display Cisco IP phone registration activity.
5. Issue the debug ip dhcp command in order to confirm the DHCP operation.
Issue the show ephone command in order to display all registered phones. If phones are registered and are displayed, then perform these tasks:
1. Check that the phone button binding to the directory number is correct.
2. Check that the Cisco IP phones show as registered.
3. Use the Settings display on the phone in order to verify the IP parameter settings on the Cisco IP phone.
4. Issue the show phone command in order to check that the keepalive count is being updated.
5. Issue the debug ephone register mac-address command in order to reset the phone and observe the re-registration. This command displays the Cisco IP phones.
6. Issue the show ephone-dn summary command in order to check the state of the Cisco IP phone lines.
7. Check the IP address of the phones and attempt to ping the addresses.
Issue the debug ephone keepalive command in order to set keepalive debugging for the Cisco IP phones.
Issue the debug ephone state command in order to set state debugging for the Cisco IP phones.
