This option allows identity certificates to be generated using the root CA certificate of the server.

Relative advantages include:

• Cost over a commercial CA.

• Control of the CA is internal.

• Certificate content format compatible with other Avaya components.

• The certificate policy is flexible and not subject to commercial considerations.

• The trust relationships do not extend outside of the deployment – that is, it remains a private domain.

Relative disadvantages include:

• The root CA certificate is untrusted by 3rd parties and other IP Office components and therefore needs to be distributed.

• The certificate creation and distribution process is manual.
