I've been a sleep at the wheel this week, busy with work, study and more work. Some interesting highlights in this release. WPA2 now supported with CCKM and Hardware Diagnostics!
Early reports from the forums I troll is that battery life appears to be less with this level of code. Also reports of better roaming are mentioned. Anyone out there testing this !? Would love to hear your feedback.
Cisco Unified Wireless IP Phones are frequently returned and a replacement is requested when the phone is operational. In firmware 1.3(4), a self-diagnostic tool is available to determine if a valid hardware issue exists.
You can access the Diagnostics menu from the Phone Settings menu, where the Keypad, Speaker, Microphone and WLAN Radio and Antenna can be validated.
The WLAN diagnostics menu is the standard site survey utility, which will use the current network profile information to scan for the configured network.
Full CCKM Support
Cisco Centralized Key Management (CCKM) reduces the amount of delay time by centralizing the key management, which reduces the number of key exchanges. To optimize secure roaming, CCKM can be enabled while in WPA or WPA2 mode.
Prior to this firmware release, CCKM was not supported when WPA2/AES was selected; this required a full re-authentication when roaming between access points, and could result in loss of audio during the roam. Now that CCKM is supported when WPA2/AES is selected, the full re-authentication is no longer required and roaming to a new access point should not result in any perceptible loss of audio.
Firmware 1.3(4) provides full CCKM support of all WPA versions.
