L2 Roaming issue with Avaya wireless phone on WISM -V6.0.196.0

Hello Friends,

I am facing Layer2 roaming issue with Avaya Wirless phone 3620 which are configured WPA / Pre-shared key auth with a SSID1 and face a cut or delay in the voice.

But when i use Cisco Wireless phones and try to roam between one LWAP to other i dont face a cut or delay in the vocie which are

Configured with 802.1x +CCKM auth .

Then i configured new SSID 3 with 802.1x+CCKM settings for the new Avaya wireless module 3631 , but still face cut and delay while doing Layer 2 roaming.

While i was using these AP in WDS mode i never faced this Layer 2 roaming issue with Avaya wireless phones.

In current WISM all the LWAPs are supporting properly to the Cisco phone and Wireless laptop clients.

I request you to please let me know how do i proceed further to solve the issue and please let me know if anybugs or incompatibility for WISM with Avaya wireless phones.

Thank you and Appreciate your response.

Regards,

Akber Mirza.
