The Branch Office IP Phones that are in Normal Mode (for example,
IP Phones registered to the main office Call Server) are checked to
see if they require a firmware upgrade. If the IP Phones require a
firmware upgrade, the IP Phones are redirected back to the Branch
Office.
The Branch Office checks its own firmware version and compares it
with the firmware version which is required by the IP Phone. If the
Branch Office does not have the required firmware, then the Branch
Office automatically initiates an FTP session to the main office and
retrieves the required firmware.
Issue the CLI command umsUpgradeAll at the Branch Office.
The IP Phones that are waiting in Local Mode receive the firmware
upgrade and are redirected back to the main office.
Upgrade the firmware at the Branch Office, in which case the IP Phones
are redirected to the main office after the upgrade.
Issue the isetResetAll command on the MG 1000B Signaling Server
maintenance terminal to redirect the IP Phones to the main office.
Action

Phones that are registered in Local Mode are upgraded.

telephones are redirected back to the TPS with the required version
of firmware.
