By securing communication with the Cisco CallManager using Secure HTTP (HTTPS), a hacker cannot listen to the data stream during HTTP sessions. In addition, in large voice environments, it is important to distribute the various administration tasks. Cisco CallManager Multilevel Administration Access allows you to assign different authorization levels to administrators. This chapter discusses both the concepts and configuration of HTTPS and MLA on your Cisco CallManager servers.
