Upgrading The Ip Telephones - Avaya G250 Installing And Upgrading

Upgrading the IP telephones

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 the G250.
Note:
An SCP server can be used for copying the script files, which do not exceed
Note:
128 KB, but cannot be used for copying image files.
You cannot use SCP to copy 46xxsettings files as they exceed 128 KB.
Note:
The G250 uses the SSH protocol to support the use of SCP for secure file
Note:
transfer. When using SCP, the G250 is the SCP client, and an SCP server must
be configured on the management station. For more information about
establishing an SCP session, see Administration for the Avaya G250 and Avaya
G350 Media Gateways, 03-300436.
1. Check the available memory size for the image files using the show
application-memory command. If the memory size needs to be changed, proceed to
step 2, otherwise proceed to step 5.
2. Set the memory size for the image files using the ip tftp-server file-system
size command.
3. Copy the running configuration to the start-up configuration using the copy
running-config startup-config command.
4. Reset the G250 using the reset command.
5. From the Avaya support site, obtain the desired phone upgrade files (script files, boot
image files, phone application image files), using either of the following methods:
- Download the phone upgrade files to a remote FTP/TFTP/SCP server. Note that SCP
can be used to download script files but not images files.
- Download the upgrade files to a laptop and copy them to a USB mass storage device.
6. Disable the TFTP server while copying new files to the device using the [no] ip
tftp-server command.
7. Copy the script files for the IP phone family.
- To copy from the remote FTP/SCP/TFTP server, use one of the following commands:
● copy scp phone-script
● copy ftp phone-script
copy tftp phone-script
●
- To copy from the USB device, insert the USB device into the G250 USB port and copy
the files to the resident TFTP server using the copy usb phone-script command.
