Upgrading Firmware of IP Phones

Upgrading Firmware of IP Phones

To upgrade the firmware of the phones through Callmaanger will need to download the new firmware from Cisco.com. Look for the correct firmware for each phone model.

In this example we will upgrade the firmware for all 7945G.

Save the downloaded file (.cop.sgn) in an TFTP server.

Log in the OS Administration and go to Install/Upgrade.

Enter with the FTP server information and the directory where the file with the new firmware was saved.

Selecionar nas opções de upgrade encontradas no servidor de TFTP qual se refere ao firmware que será atualizado. Verifique o checksum e inicie a atualização.

Select in the Options/Upgrades the file which refers to the new firmware .

Check the checksum and then start the upgrade.

Installation of the new firmware completed.

Verify if the new firmware information were replicated in Callmanager after the upgrade process. To do this log in Callmanager Administration, go to Device Default and find the model 7945.

Make sure that the firmware name matches with the name of the updated versions downloaded from Cisco.com.

Reset the phones. After that they`ll reload with the new firmware.
