Select certificate authorities for a SIP line

CIC provides a default line authority certificate for use with every SIP line. You can select additional certificate authorities if you plan to use an external third-party certificate authority to sign line certificates.

The third-party certificate authority files must be generated and copied to the CIC server before you can select them for a SIP line.

To select certificate authorities for a SIP line

Open the TLS Security tab of the Line Configuration dialog box.

Note: In order to access the TLS Security tab, you just first select TLS as the transport protocol on the Transport tab.
Click Modify.
The Select the certificate authorities for this line dialog box appears.
To select a certificate authority, select it in the Available list and then click Add.
To deselect a certificate authority, select it in the Currently Selected list and then click Remove.
Click OK.
