Hello All, we just recieved the CP-7945 phones. One of the phone on connecting is trying to upgrade the firmware. The current firmware on the phone is 9-3-1. The latest which i can download from cisco website is 9-2-1 which will not work in my case. So i need your suggestions for this issue.

The Cisco 79xx IP phone series support 2 protocols: SCCP (skinny) and SIP. By default the phones are working with SCCP. The way to get the Cisco phone to work with VoIP is to load the SIP firmware into the phone and then configure the extension.

For this to work you need a TFTP server plus a DHCP with option 150 enabled – an option to auto-provision the TFTP server IP address when the DHCP server hands out the regular ip address to the phone. Without an auto-provisioned TFTP server address, the phone will only complete half the upgrade and come up with an error message of “protocol application invalid.” This just means that the phone could not complete the second half of the upgrade and needs the TFTP IP address to be specified. Force op no survey.

Only problem is since there is no application running, there is no place to specify the address! Thank goodness for DHCP option 150 which does this for us when the phone grabs an IP address after loading the bootloader.en the phone grabs an IP address after loading the bootloader. Below are instructions to upgrade/convert any Cisco 7940, 7941, 7942, 7945, 7960, 7961, 7962, 7965, 7970 and 7971 IP phones to any firmware you want from the Cisco web site (SIP/SCCP), and to recover any Cisco phone which may have screwed up somehow while upgrading firmware (like if you get the protocol application invalid message). Step 1: Upgrading to SIP firmware 8-12-00 • Download SIP firmware 8.x from CCO Cisco Web site. Note: You need to be a registered Cisco partner with a valid service contract otherwise you cannot download it directly from Cisco website, If you do not have a valid service contract you can click the link below: • Cisco 79xx firmware files download • Download the.zip file and extract it into your TFTP root directory.

(See next step) Step 2: Download and configure the DHCP/TFTP server • TFTP/DHCP server under windows: • Go here to download the TFTP/DHCP server – • Download and install version 3.23.

Code: # /etc/init.d/dhcp3-server restart # /etc/init.d/tftpd-hpa restart Step 3: Configuration • Download the file XMLDefault.cnf.xml from and copy/paste it in to the TFTP boot folder (/var/lib/tftpboot) • make sure you write the correct firmware filename in P0S3-8-12-00 • Download SEP.cnf.xml from and put it in firmware directory. • You must put the MAC address of each phone in the file (eg. Note that for every phone you need one file with the MAC address of the phone. • Download the file dialplan.xml from and copy it into the firmware directory. Example dialplan.xml. Code: Step 4: Factory reset the phones and start configuration Power Cycle the phone. Hold down the # key then power on the phone.

When the light blinks on the phone line button, release the # key, then follow by pressing 123456789*0#. The firmware you put in the tftp root folder will start loading. Once firmware upgrading finishes, verify the new SIP firmware version. Press “setting” then select: • Device Configuration > SIP Configuration • Model Information > Load File, Boot Load ID • Status > Firmware Version. Paul, Brilliant article but for some reason when I get to 3: Configuration 1.Download the file XMLDefault.cnf.xml from here and copy/paste it in to the TFTP boot folder (/var/lib/tftpboot) ◦make sure you write the correct firmware filename in P0S3-8-12-00 2.Download SEP.cnf.xml from here and put it in firmware directory. ◦You must put the MAC address of each phone in the file (eg.
