Telepresence & Encryption with CUCM

[Gordon Ross]

I'm running CUCM 12.5 in mixed-mode. I've configured and enabled encryption for handsets fine. But when I configure a telepresence units (Roomkit, DX, etc on CE9.8) with any form of encryption, the unit fails to register.

I can't see anything on Cisco.com specifically about enabling encryption for telepresence units. Has anyone got any pointers?

Thanks,

Hello

are you provisioning your endpoint with CUCM?

If not it will not be able to download LSC. Also one more thing are you using thrid party CA for CUCM certificates?

If yes do you added the root cert on endpoints (in ideal cases not required but it helps if endpoint in not securely registering )

Also on phone page of CUCM under CAPF config try install /upgrade and then save the config and reset and see if it pushes the certs to endpoint.

You can check the cert under endpoint web gui --> security --> CUCM certificate.

Thanks
