Brief Overview of the Cisco Unified Border Element

The Cisco Unified Border Element is used to create secure connections between different networks, and to establish and maintain the routing between these networks. Typically, Cisco Unified Border Element customer networks are based on SIP-dialed numbers.

The Cisco Unified Border Element provides secure transport of media, such as video and audio, from one network to another, using call policies and Call Admission Control (CAC) policies. These configurable policies allow customers to control the volume of calls per customer and to restrict certain types of calls.

The two primary elements of a Cisco Unified Border Element configuration are call policies and CAC policies. A call policy handles number analysis and routing. A CAC policy controls call admissions only.

Figure 1 shows the order in which number analysis, routing, and CAC occur during a new call.
