The Cisco Unified Border Element SP Edition is a high-scale, carrier-grade session border controller (SBC) that is integrated into Cisco routing platforms; it can be integrated with many router functions to provide a very feature-rich and intelligent SBC application. 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 (QoS), Call Admission Control (CAC), and bandwidth management.

Cisco Unified Border Element SP Edition allows service providers and large enterprises to connect isolated voice, video, and unified communications networks directly over IP-IP interconnections, avoiding public switched telephone networks (PSTNs). End-to-end IP enables services such as Session Initiation Protocol (SIP) trunking, service provider voice-over-IP (VoIP) peering, residential triple play (data, voice, and video), and business-to-business Cisco TelePresence conferencing
