The Cisco Unified Border Element (Enterprise) on the Cisco ASR 1000 brings a scalable option for enterprise customers. Running as a process on the Cisco ASR 1000 and utilizing the high-speed RTP packet processing path, the Cisco Unified Border Element (Enterprise) is used as an IP-to-IP gateway by enterprises and commercial customers to interconnect SIP and H.323 voice and video networks. The Cisco UBE (Enterprise) provides a network-to-network demarcation interface for signaling interworking, media interworking, address and port translations, billing, security, quality of service (QoS), and bandwidth management. |
|
The Cisco Unified Border Element (SP Edition) is a session border controller (SBC) that is VoIP-enabled and deployed at the edge of networks. For Cisco IOS XE Release 2.3 and earlier releases, Cisco Unified Border Element (SP Edition) is supported only in the distributed mode. Operating in the distributed mode, the SBC is a toolkit of functions that can be used to deploy and manage VoIP services, such as signaling interworking, network hiding, security, and quality of service. |
|
The Cisco Unified Border Element (SP Edition) is a highly scalable, carrier-grade session border controller (SBC) that is designed for service providers and that is generally deployed at the border of the enterprise or SP networks to enable the easy deployment and management of VoIP services. Cisco Unified Border Element (SP Edition) is integrated into Cisco routing platforms and can use a large number of router functions to provide a very feature-rich and intelligent SBC application. Formerly known as Integrated Session Border Controller, Cisco Unified Border Element (SP Edition) provides a network-to-network demarcation interface for signaling interworking, media interworking, address and port translations, billing, security, quality of service, call admission control, and bandwidth management. For Cisco IOS XE Release 2.4 and later releases, Cisco Unified Border Element (SP Edition) can operate in two modes or deployment models: unified and distributed. The configuration guide documents the features in the unified mode. |
