how to upgrade IP Phone 7945 firmware?

[sia]

hello everyone

I have a phone IP Phone 7945, I did a factory reset.

now I want to upgrade it to a firmware I have downloaded from the internet.

what i did:

create a DHCP server on a Mikrotik router

i have added option 150 ,

installed filezilla server

now when the phone boot up, it shows the IP itself instead of showing my laptop IP which is the TFTP server.

how to work around this, please?

your help is much appreciated.

regards

Why not just install the files to your CUCM TFTP server? Install the 6 files for the version you have, which would look something like this: apps45.9-4-2ES25 cnu45.9-4-2ES25 cvm45sip.9-4-2ES25 dsp45.9-4-2ES25 jar45sip.9-4-2ES25 SIP45.9-4-2ES25S Doing that will only install the files and not change the existing device defaults (though it is always a good idea to double check anyway). Once you have the files installed then you can go to the phone configuration page and specified the phone load name, which will look like this: SIP45.9-4-2ES25S Something else to consider is the compatibility of the firmware you are trying to run along with the hardware version of the phone. Newer hardware versions will not be able to run older versions of firmware (i.e. hardware 13 or higher must run firmware 9.3(1) SR1 or higher).

Do you have a SEPmacaddress.cnf.xml file?

[sia]

no, I don't, and what this file does please?

[Leo Laohoo]

SEPmacaddress.cnf.xml file is the config file for the phone. In it is an XML tag telling the phone what firmware it needs to run.

where i can get it? and how to use it?

If you know the IP address of the TFTP server your CUCM cluster uses, you can use an application called "free ftpd".  When you open it, click on the "Tftp client" tab and fill in the fields as such:

Host - ip address of the tftp server

Port - 69

Local file - sep<mac address>.cnf.xml

Remote file - same as the local file

Click on "Get" once you have the information filled in.  You may have to click "Get" a couple times to pull the configuration but once you do you will get a message that states something along the lines of: "30 blocks transferred in 1 second".  Then you can pull the file from your machine and view it.  Make sure to open the file using Notepad++ for best view.

Once you have the config file, look for the line that defines the load information:

<loadInformation>sip8845_65.10-3-2-16</loadInformation>

Update the load name to the firmware version you want, save it to your laptop, and have your phone try to pull it down.

thanks a lot for your link, i did what is there but still not success.

below is the screenshot of my phone when it boots up, it show the IP address of the phone it self instead of the Tftp server

the 192.168.88.250 is the IP address of the phone

the 192.168.88.11 is the IP address of my laptop which i assume should be the IP of the tftp server.

please correct me if im wrong , 

on mikrotik router i have add option 150 with the IP 192.168.88.11 converted to hex

IP address should not be expressed as HEX.

[sia]

Than you for the reply
But according to the Mikrotik instruction it need to be converted to hex.
Another thing the IP which appeared in my phone should be the IP of my laptop?
