Maintenance and diagnostics

The administrator enters

umsUpgradeAll

command at the main office.

The firmware version on the Normal Mode Branch Office IP Phone is
compared to the firmware policy of the main office. If the firmware is the
same as the main office, no firmware update is required. If the firmware is
different, the IP Phones are redirected to the Branch Office.

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 Phones 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
Phone registers with a TPS, the TPS checks the firmware version in the IP
Phone. If the firmware version differs from that required by the Signaling
Server (or the Media Card) 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 Phone firmware in the TPS is upgraded, the IP Phones 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 Phones that do not have
the latest firmware files. However, firmware download is automatic for IP
Phones that register to the TPS after the upgrade.

umsUpgradeAll

Firmware download does not happen when Internet Telephones register to
the LTPS by a Virtual Office Login or Branch Office redirection to the Main
Office. Instead, Branch Office Internet Telephones 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 currentfirmware version does not match the Main Office LTPS firmware
policy.does not match the main office TPS firmware policy.

If an IP Phone 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 Phone is flagged,
then redirected to the MG 1000B TPS when the call is completed.
