Encryption for Cisco IP Phone 6921

Guys,

Need your help here ....

Have you been implemented encryption for Cisco IP Phone 6921 ? (Use CTL Client based on http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/security/8_5_1/secugd/secuauth.html)

I have some issue here, i can and already implement encryption for Cisco IP Phone 7945, 7965 and 9971. But for Cisco IP Phone 6921 i can't implement it. I read from Cisco Datasheet 6921, it says that Cisco IP Phone 6921 support voice encryption. When i try install LSC (Locally Significant Certificate) in Cisco IP Phone 6921, it doesn't success.

Is there any of you have some experience like this ? It work for other phone, but not for Cisco IP Phone 6921.

BR,

Rizal Ferdiyan
