Cisco CallManager Release 4.0 and later supports many security features that are based on a Public Key Infrastructure (PKI) solution. In earlier releases, Cisco CallManager did not use PKI-like features, and many Cisco CallManager administrators are not familiar with PKI. This chapter discusses the concept of a PKI, its components, and its applications.
