Digital certificates can be used to authenticate network devices and users on the
network. They can be used to negotiate IPSec sessions between network nodes.
A third party uses a Certificate Authority Certificate to validate and authenticate
two or more nodes that are attempting to communicate. Each node has a public
and private key. The public key encrypts data. The private key decrypts data.
Because the nodes have obtained their certificates from the same source, they are
assured of their respective identities.
The device can use digital certificates provided by a third-party Certificate
Authority (CA) to authenticate IPSec connections.
To enable and configure a custom certificate of authority:
Click Admin Login > advanced > Voice > Provisioning.

• URLs
• Multistage provisioning status information
• Post request templates
