Upgrading an IP phone

Last Updated : Jun 17, 2021 |

About this task

IP phone upgrade files include script files, boot images files, and phone application image files. You can download these files to a remote FTP/TFTP/SCP server, or you can download them to a laptop and copy them to a USB device. You can then copy the upgrade files to Branch Gateway.

An SCP server can be used for copying the script files, which do not exceed 128 KB, but cannot be used for copying image files. You cannot use SCP to copy 46xxsettings.txt files as they exceed 128 KB.

Branch Gateway uses the SSH protocol to support the use of SCP for secure file transfer. When using SCP, Branch Gateway is an SCP client, and an SCP server must be configured on the management station.

For more information about establishing an SCP session, see Administering Avaya G450 Branch Gateway.

      • copy scp phone-script

      • copy ftp phone-script

      • copy tftp phone-script

    • To copy from the USB device, insert the USB device into a Branch Gateway USB port and copy the files to the resident TFTP server using the copy usb phone-script command.

  5. Copy the boot image files for up to two IP phone types:

    • To copy from the remote FTP/TFTP server, use either the copy ftp phone-image command or the copy tftp phone-image command for each IP phone type.

    • To copy from the USB device, insert the USB device into a Branch Gateway USB port and copy the files to the resident TFTP server using the copy usb phone-image command.

  6. Copy the phone application image files for up to two IP phone types:

    • To copy from the remote FTP/TFTP server, use either the copy ftp phone-image command or the copy tftp phone-image command for each IP phone type.

    • To copy from the USB device, insert the USB device into a Branch Gateway USB port and copy the files to the resident TFTP server using the copy usb phone-image command.

  7. Reset the phones and wait for the installation to be completed.

    Once the upgrade procedure is complete, you can delete the files using the erase phone-image command.
