Third-party certificate signing concepts

You can sign a certificate from a third-party device (for example an Audiocodes Mediant gateway) that uses the CIC authority certificate.

This is necessary when you configure a SIP line that uses TLS to connect to a third-party device that supports TLS. The connection between the CIC server and the third-party device needs to be authenticated when it establishes a connection that uses mutually authenticated certificates. If the device's certificate is not signed by the CIC line authority certificate, the connection will not be authenticated.

Note: Use the Third Party Certificate Signing tab only if you use the CIC line authority certificates. Do not use it if you have your own third-party certificate authority.
If you use your own third-party certificate authority and line certificates, then you must use your own certificate signing utility to sign the third-party device certificate.
