Description
This section applies only to the main office CS 1000 Release 4.5 and the
following IP Phones:
• IP Phone 2001
• IP Phone 2002
• IP Phone 2004
• IP Phone 2007
Note: It does not apply to the IP SoftPhone 2050 and WLAN 2210/
2211.
The redirected IP Phones at the SRG50 are under the control of the main
office Call Server for the majority of the deployment (Normal Mode). Users
of the SRG IP Phones receive the features, key layout, and tones of the main
office Call Server. Therefore, the version of the IP Phone firmware must align
with the requirements of the CS 1000. When an IP Phone requires firmware
upgrade, the CS 1000 uses the umsUpgradeAll command, or variant, to
redirect the IP Phone back to the SRG50 for upgrading.
