Chapter 4 CS 1000 considerations 51
Firmware upgrade
The redirected IP telephones at the SRG are under the control of the main office call server for the majority of their deployment and receive all of their features in that context. Therefore, the version of IP set firmware must align with the requirements of the CS 1000.
Supported firmware
The table Supported IP clients and firmware versions on page 51 lists the IP clients and related firmware versions supported on the SRG50. The SRG50 column indicates the firmware versions included with the SRG software. The CS 1000 columns identify the version of firmware to use for specific releases.

Firmware upgrade procedure
When an IP telephone requires a firmware upgrade, the CS 1000 uses the umsUpgradeAll command, or variant, to redirect the telephone back to the SRG for upgrading. If the required file does not exist on the SRG, or its version is incorrect, the SRG initiates an FTP session to the TPS for that phone to retrieve the required file. The SRG upgrades the phone and redirects it back to the CS 1000. After the SRG receives new firmware from the Main Office for a specific IP telephone, all the IP telephones of the same type are loaded with the new firmware.
