How to upgrade or convert a Cisco Ip 7. SIP or SCCPGetting Cisco phones working with asterisk may seem like a daunting procedure; getting SIP firmware installed on the phone, loading up the the firmware files in the tftp server, fearing that you will somehow brick the phone by an incomplete firmware upload.

They just need a tftp server to update its firmware and it doesnt even have to be located on the asterisk/phone system itself. Cisco phones update in two stages. The bootloader, then the application. Once the bootloader is upgraded, all passwords and networking information on the phone will be wiped out.

But what is essential in upgrading these phones is a DHCP server with option 1. 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. Only problem is since there is no application running, there is no place to specify the address! Thank goodness for DHCP option 1.

IP address after loading the bootloader. Below are instructions to upgrade/convert any Cisco 7. IP phone 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: Download Cisco phone firmware.

Cisco may require you to have a smartnet contract before you download the firmware, but if you do not have one, there are firmware files available on the internet. Ive provided two sources below. Goto http: //www. Download the firmware for the specific phone you are using. Download the . zip file and extract it to a directory.

Extracted files in a folder. You will have several files in this directory. If you just have one, you must remember to extract all the files. Step 2: Download and configure the DHCP/TFTP server. We are going to use a windows based machine and load tftp/dhcp software on it which will make our windows machine a server for our phones. Go here to download the tftp/dhcp server – http: //tftpd.

Download and install version 3. YOU MUST DOWNLOAD AND INSTALL THIS VERSION. I have had many people complaining about their phones not obtaining a correct ip address and also the files not being sent correctly. Every one of these problems was due to using the incorrect version and/or having their firewall on). You will also have to configure your windows machine to use ip address of 1.

Youll configure this tftp server to host the upgrade files via tftp server (theres an option to configure the working directory in the program to use for the stored firmware files on the windows machine – this must be set correctly!).

Power Cycle the phone and clear the configuration by holding down the # key and then plugging in the phone. After all the lights cycle on the phone, release the # key and press 1.

The lights will turn red, but if they dont, repeat this step. The phone will then wipe the flash and load whatever firmware is specified in the tftpd.

This will clear all settings on the phone and set it to defaults. Upon reboot, the phone will grab an ip address from the dhcp server on the windows machine running the dhcp server.

Information tag with the POS- xxx filename which is located in that directory and  reboot the phone. The phone will automatically switch over to loading the SIP firmware. You can check the events viewer within tftpd.

If the phones just sit like they arent doing anything, wait a bit longer and they should come back up. Its not uncommon for one phone to take up to 4- 5 minutes to complete the entire process. Thats all there is to it, and now that the phone has a good universal application bootloader, you will have no trouble switching between SCCP and SIP by just pointing the phone to the appropriate directory.
