The Cisco Unified Border Element (Cisco UBE) is an intelligent unified communications network element.
Formerly known as the Cisco Multiservice IP-to-IP Gateway, the Cisco Unified Border Element, in addition to
other Cisco IOS Software features, includes session border controller (SBC) functions that enable end-to-end
IP-based transport of voice, video, and data between independent unified communications networks. SBCs are
critical components for scaling unified communications networks from being “IP islands” within a single
customer network to becoming an end-to-end IP community. One of the most significant uses of the Cisco
Unified Border Element is to allow call-control elements such as Cisco Unified Communications Manager to
connect to service providers for public-switched-telephone-network (PSTN) access offerings over Session
Initiation Protocol (SIP) trunks. Today, the Cisco UBE is used as an IP-to-IP gateway by service provider,
enterprise, and commercial customers to interconnect SIP and H.323 voice and video networks.
Ideal for Companies That Need These Features
Key Features
The Cisco Unified Border Element delivers the following features and benefits:
• Essential network border security features
• Privacy features for hiding internal network address structure from other administrative domains
• Layer 7 application layer gateway features
• Interworking features for interconnecting different voice-over-IP (VoIP) network types, such as H.323-to-SIP
• Dual tone multifrequency (DTMF) interworking
• Capacity control and improved call routing control using carrier-based routing
• Codec filtering by restricting codecs advertised on outbound call legs
• Billing and settlement features
• Software and hardware media-termination-point (MTP) functions for Cisco Unified Communications
Manager (applies to Cisco 2800 and 3800 Series Integrated Services Routers only)
• Support for changing codecs during rotary dial-peer selection
• Simultaneous operation with TDM gateways on Cisco integrated service routers, permitting graceful
migration from TDM to IP trunking
• Support for Lawful Intercept capabilities
• Support for Open Settlement Protocol
• Configurable Session Initiation Protocol (SIP) trunk profiles support
• Available in various licensing configurations to match customer capacity and price-point needs
