If you mean for IP Phones, there's a list of what root CAs are loaded in the phones and you can only use a CA from that list as you cannot load root CAs to phones.

If you mean for Jabber, there is no list of tested CAs, it should work fine as long as they provide the right key usage and you send the proper CSR for your deployment.

Hi @ibrahim.kayali,

Specific to Comodo, yes it does support it as it is listed under the Pre-Installed CAs of Cisco Telepresence Endpoints.

You can check it by following these steps :

• Sign in to the web interface of Endpoint, navigate to Configuration > Security, and open the Preinstalled CAs tab.

About pre-installed certificates:

The pre-installed certificates in this list are only used when the video system is provisioned by Cisco Unified Communications Manager (CUCM) via Expressway (Edge).

Only Cisco Expressway infrastructure certificates are checked against this list.

If the validation of the Cisco Expressway infrastructure certificate fails, the video system will not be provisioned and registered.

Factory resetting the video system does not delete the list of pre-installed certificates.

As an alternative to using the pre-installed certificates, you can append the certificate you need to the certificate list manually.

Rishabh Gupta.
