Introduction

This document is intended to detail a simple method for Switching between the SIP and SCCP 7940G, 7960G IP Phones with the Firmware upgrade procedures.


Firmware Upload procedure for 7940G and 7960G


This document is intended to detail a simple method to upgrade firmware on the 7940G and 7960G IP Phones. In this method Cisco Unified Communication Manager Express, CUCME or CME is used and to configure TFTP server with all of the appropriate phone load files already in flash.

In the example shown below we are starting with a 7960G phone with a SCCP load 5.0 (4.0). The firmware upload procedure detailed below will work for any SCCP load. SCCP firmware loads always begin with the following 3 characters: P00….and SIP firmware loads always begin with the following 3 characters: P0S…

1. Upgrade from SCCP 5.x/7.x to SCCP 8.x

You cannot upgrade directly to a SIP load from some of the earlier SCCP loads. For this reason we are going to upgrade our SCCP load before attempting to put the SIP firmware onto the phone. We must first setup the TFTP server so that the CME router can allow the phone to download the necessary files.

tftp-server flash:PHONE/7940-7960/P00308000500.bin alias P00308000500.bin

tftp-server flash:PHONE/7940-7960/P00308000500.loads alias P00308000500.loads

tftp-server flash:PHONE/7940-7960/P00308000500.sb2 alias P00308000500.sb2

tftp-server flash:PHONE/7940-7960/P00308000500.sbn alias P00308000500.sbn

We are going to use the telephony-service to upgrade firmware. The TFTP address of the phone that will have new firmware downloaded should be set to the CUCME ip address. We need to get a basic telephony-service configuration on the CME. The telephony-service must be allowed to create configuration files dynamically. We then need to add the MAC address and phone type to an ephone.

Sample Configuration

telephony-service

no auto-reg-ephone ! we don’t want to upgrade other phones accidentally

max-ephones 2 ! number of phones you are upgrading

max-dn 2

ip source-address 10.10.110.3 port 2000 ! ip address of your CME router

load 7960-7940 P00308000500 ! firmware load you are upgrading to

create cnf-files

!

ephone 1

mac 1111.2222.3333 ! MAC Address of the 1st phone you are upgrading

type 7960

!

ephone 2

mac 4444.5555.6666 ! MAC Address of the 2nd phone you are upgrading

type 7960

Once this configuration is complete, reboot the phone. The output below shows the TFTP cycle the phone goes through over the next 5 minutes or so.

Once the phone is registered, confirm the phone load by looking on “Firmware Version” from the phone itself (or by using the following command):

RTR#sh ephone phone-load

DeviceName CurrentPhoneload PreviousPhoneload LastReset

=====================================================================

SEP000D299D3284 8.0(5.0) 5.0(4.0) Initialized

2. Upgrade from SCCP 8.x to SIP 8.x

You cannot upgrade directly to a SIP load from some of the earlier SCCP loads. For this reason we are going to upgrade our SCCP load [Follow the steps, section titled “Upgrade from SCCP 5.x/7.x to SCCP 8.x” above] before attempting to put the SIP firmware onto the phone. We must first setup the TFTP server so that the CME router can allow the phone to download the necessary files.

Now it is time to upgrade to SIP. First setup the TFTP server on the CME router to allow the phone to download the necessary files.

tftp-server flash:PHONE/7940-7960/P0S3-08-6-00.loads alias P0S3-08-6-00.loads

tftp-server flash:PHONE/7940-7960/P0S3-08-6-00.sb2 alias P0S3-08-6-00.sb2

tftp-server flash:PHONE/7940-7960/P003-08-6-00.bin alias P003-08-6-00.bin

tftp-server flash:PHONE/7940-7960/P003-08-6-00.sbn alias P003-08-6-00.sbn

Remove the ephone configuration and disallow the CME from creating configuration files dynamically.

Sample Configuration

RTR#(config)#no ephone 3

RTR#(config)#telephony-s

RTR#(config-telephony)#no create cnf

Then configure the voice register settings as shown below.

voice register global

mode cme

source-address 10.10.202.1 port 5060 ! IP Address of CME

max-dn 2

max-pool 2

load 7960-7940 P0S3-08-6-00 ! SIP firmware load you are upgrading to

tftp-path flash:

create profile

You will see the following output as the phone downloads the new firmware.

3. Upgrade from SIP To SCCP

Ensure that there is no voice register pool for the device you are trying to upgrade. If there is a voice register pool then delete it and make sure you “create profile” within voice register global. The next step is to add the correct SCCP firmware in the load statement within telephony-service.

Sample output

telephony-service

load 7960-7940 P00308000500

load 7962 SCCP42.8-3-3S

Ensure that the relevant “tftp-server” commands are entered into configuration on the router. See below for the best way to add this.

You need to change the path to reflect the correct directory structure that is preloaded onto the flash- the word “phone” needs to up upper case “PHONE”. So in effect to register a 7960 and 7962 you would need these commands:

4. Add the ephones with the correct MAC Address and phone type

Sample Output

ephone 1

mac-address 0017.94CF.219E

type 7960

button 1:1

!!!

ephone 2

mac-address 0021.A086.7F8E

type 7962

button 1:2

This will result in the following SEP files pointing to the system XMLDefault files. Each of the XML Files (XMLDefault, XMLDefault7960 and XMLDefault7962) have the correct load information set for the appropriate phone.

RTR#sh telephony-service tftp-b

...

tftp-server system:/its/vrf1/XMLDefault.cnf.xml alias

XMLDefault.cnf.xml

tftp-server system:/its/vrf1/XMLDefault7960.cnf.xml alias

tftp-server system:/its/vrf1/XMLDefault7962.cnf.xml alias

...

If we look into this file you will see the load information correctly set.:

RTR#more system:/its/vrf1/XMLDefault7962.cnf.xml

<loadInformation>SCCP42.8-3-3S</loadInformation>

After a certain amount of time the phone will request the configuration file:
