• Firmware retrieval mechanism described for the Branch Office LTPS
retrieves only firmware files it finds missing. It does not compare the list
of firmware on the Branch Office LTPS and Main Office LTPS to
determine whether the Branch Office has the latest firmware, or perform
any automatic compare and update operations. The Branch Office LTPS
only receives firmware files when the umsUpgradeAll command was
issued on the Main Office LTPS.
Feature interactions
Active Call Failover for IP Phones
The Active Call Failover feature handles cases when an IP Phone registers
with an active RTP stream (has a call active at the time of registration). The
check of IP Phone firmware is skipped in this case, and the IP Phone registers
with the LTPS.
The Active Call Failover scenario is the same as the postponed firmware
upgrade scenario described in Table 19 on page 114. After the call ends, the
user is prompted to start the firmware upgrade.
For more information on Active Call Failover for IP Phones, refer to “Active
Call Failover for IP Phones” on page 75.
