Maintenance and diagnostics
The firmware files are transferred from the main office to the Branch Office by FTP. Once the files
have successfully been transferred to the Branch Office, the umsUpgradeAll command is invoked
on the Branch Office. All IP Deskphones waiting for the firmware are automatically upgraded and
returned to the main office.
The firmware retrieval mechanism for the Branch Office TPS retrieves only firmware files it finds
missing.
It does not compare the list of firmware on the Branch Office TPS with the main office TPS to
determine whether the Branch Office has the latest firmware, nor does it perform any automatic
compare and update operations. The Branch Office TPS only receives firmware files when the
umsUpgradeAll command is issued on the main office TPS. When an IP Deskphone registers with
a TPS, the TPS checks the firmware version in the IP Deskphone. If the firmware version differs
from that required by the Signaling Server and the firmware upgrade policy requires an upgrade, the
firmware is downloaded to the telephone. The telephone reboots after the firmware download is
complete and registers with the TPS again.
When the IP Deskphone firmware in the TPS is upgraded, the IP Deskphones that registered with
the Call Server before the upgrade are not affected. The system administrator must execute the CLI
command umsUpgradeAll to download the firmware to all registered IP Deskphones that do not
have the latest firmware files. However, firmware download is automatic for IP Deskphones that
register to the TPS after the upgrade.
Firmware download does not happen when IP Deskphones register to the LTPS by a Virtual Office
Login or Branch Office redirection to the Main Office. Instead, Branch Office IP Deskphones are
redirected back to the Branch Office LTPS for firmware upgrade. This redirection occurs only if the
umsUpgradeAll command is issued from the Main Office LTPS, and the current firmware version
does not match the Main Office LTPS firmware policy.
If an IP Deskphone is in use when the umsUpgradeAll command is issued, the call is not
interrupted. Its firmware version is checked against the main office TPS firmware policy, and if there
is no match, the IP Deskphone is flagged, then redirected to the MG 1000B TPS when the call is
completed.
The umsUpgradeAll command has no immediate impact on IP Deskphones that are logged in or
out by Virtual Office. However, the firmware files can be upgraded, if required, when the Virtual
Office session is terminated.
For information on Enhanced UNIStim Firmware, refer to Avaya Signaling Server IP Line
Applications Fundamentals, NN43001-125.
Each IP Deskphone that is redirected back to the Branch Office has its firmware version checked
against the MG 1000B TPS firmware policy. If there is no match, the firmware is upgraded
automatically and the IP Deskphone is redirected back to the main office. If there is a match, the IP
Deskphone stays in Local Mode, and Required firmware <version> is displayed on the
telephone screen (see
