348 Maintenance and diagnostics
3 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.
4 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.
5 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.
—End—
For Branch Office systems running CS 1000 Release 4.0 and earlier
software, always upgrade the MG 1000B TPS before the main office TPS.
Otherwise, the MG 1000B TPS does not have the required version of
firmware for upgrading the telephone. The IP Phone stays in Local Mode
with the required firmware files displayed (see
"Troubleshooting" (page
349) ). The system administrator has two options:
• 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.
Procedure 46

Phones that are registered in Local Mode are upgraded.
