Phones Trust Store for 8851 and 8861, adding my own root certificates.

[Juan Gerardo Hernandez]

I have some phones, I am playing with TLS and CA.

It is possible to add my root certificates from my home CA into the 8851 and 8861? I want that when a CA signed certificate is presented to the phone, the phone Trust it and stablish a TLS connection.

If that is possible from the CUCM? or is that possible if I install the MPP firmware to the phone?

Thank you very mucho,.

You can load certs to the "phone-trust" via CUCM osadmin.

But where should the phone establish a TLS connection to?
Normally, the phones only talk with CUCM, to encrypt SIP over TLS, or HTTPS for phone services.
So personally, I don't really get the use case you are trying to achieve ...
