Changing web security parameters (ou, l, o) affect telephones already registered using self-signed cerficate?

Hi,

We want to use a CA signed certificate but we were told to modify certain web security parameters like organizational unit (ou) that we used during initial cucm installation proccess. We are not sure if these parameters are use to generate the CTL file that is initialy downloaded to telephones. We want to be sure that if we modify these parametes via CLI to generate the new certificate we don´t affect telephone registration or functionality.

We hope you can help us.

Ray,

The system uses this information to generate certificate signing requests (CSRs), which are used to obtain third-party certificates:
