206 Enhanced UNIStim Firmware Download
For CS 1000 Release 4.5 and later, if the required firmware file does not
exist on the SRG 50, or the version of the file is incorrect, the SRG 50
initiates an FTP session to the TPS for the IP Phone to retrieve the required
file. The SRG 50 upgrades the IP Phone and redirects the IP Phone back
to the CS 1000.
For SRG 50 Release 2.0 and later, if the required firmware does not exist
on the SRG 50, or the version is incorrect, the SRG 50 initiates an FTP
session to the TPS for the IP Phone to retrieve the required file. The SRG
50 upgrades the IP Phone and redirects the IP Phone back to the CS 1000.
For SRG 50 Release 1.0, the SRG 50 must be patched to the proper
firmware level with patch number BCM50.90. For CS 1000 Release
4.0, ensure MPLR21148 is installed on the Signaling Server. Firmware
download does not occur when IP Phones register to the TPS by a Virtual
Office Login or branch office redirection to the main office. Instead, SRG
IP Phones are redirected back to the SRG TPS for firmware files upgrade.
This redirection occurs only if the umsUpgradeAll command is issued from
the main office TPS, and the current firmware files are missing.
For CS 1000 Release 4.0, ensure MPLR21148 is installed on the Signaling
Server.
Firmware download does not occur when IP Phones register to the TPS by
a Virtual Office Login or branch office redirection to the main office. Instead,
SRG IP Phones are redirected back to the SRG TPS for firmware files
upgrade. This redirection occurs only if the umsUpgradeAll command is
issued from the main office TPS, and the current firmware files are missing.
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. The
umsUpgradeAll command has no immediate impact on IP Phones that
are logged in or out by Virtual Office. However, the firmware files may be
upgraded, if required, when the Virtual Office session is terminated.
