Condition

TFTP is not supported by TPS for firmware upgrades. UFTP can be used instead.
If it is required to adjust UMS policies for some reason, this should be done on all servers one by one.
The following issue may be encountered when attempting to upgrade i2007 endpoints:
An i2007 endpoint with a legacy 3.x firmware reboots after registering on a CS 1000 system. The endpoint displays a message about a firmware upgrade to a newer firmware provided by a signaling server and reboots without an actual upgrade. This continues until the UMS policy is adjusted to prevent further upgrades. Attempts to upgrade the endpoint over TFTP fails as well.

Cause

A two-step upgrade may be required for upgrading from legacy 3.x releases to 5.x. This is applicable to the i2007 because of changes in the memory structures. An intermediate 3.2+ firmware must be used for this upgrade.

Solution

  1. Install C6R firmware for the i2007 on the appropriate signaling server.
  2. Upgrade the endpoint C6R. Install C96 or newer firmware the i2007.
  3. Upgrade the i2007 to the latest firmware.
