Acquiring a certificate
As noted in the previous exercise, you will need to acquire a Unified Communications
certificate from a trusted third-party CA. DigiCert ( http://www.digicert.com ) is an example of a
trusted third-party CA. We will use DigiCert as a CA for this part of the exercise, although
you are free to use any trusted third-party CA.
This portion of the exercise might vary depending on which CA you use:
1. Visit the website of your CA. We logged on to our DigiCert account and chose to
purchase a Unified Communications certificate. It is important that you select the
correct certificate type, as shown in Figure 11-29.
