Unified Communications
Cisco integrated services routers provide a unique platform for media-rich collaboration experience, including voice,
video, and data across business, government agency, and institutional workspaces. The security, resilience, and
scalability of the network enables users in any workspace to connect everywhere, every time, and everyone. As
shown in Figure 2, the Cisco 3800 Series meets the Unified Communications needs of midsize to large enterprise
branch offices, while delivering industry-leading security within a single routing platform. With embedded voice
services inside the router, you have maximum deployment flexibility, plus higher densities for stations, trunks, and
conferencing.
Unified Communications (UC) is enabled via a rich signaling and media processing infrastructure, including a variety
of protocols, media interworking, signal and media security, transcoding, conferencing, and quality of service. Cisco
integrated services routers feature the widest range of voice-gateway interfaces, supporting a broad array of
signaling and physical network interfaces. In addition, the Cisco Unified Border Element (CUBE) enables IP trunking
capability. CUBE functions provide a network-to-network demarcation and interface point for billing, security, call
admission control (CAC), quality of service (QoS), and signal interworking.
Cisco integrated services routers offer the award-winning Cisco Unified Communications Manager Express
(CUCME) IP telephony solution for wired and cordless wireless LAN (WLAN) phones. For larger, centralized Unified
Communications deployments employing Cisco Unified Communications Manager, one can deploy Cisco Unified
Survivable Remote Site Telephony (SRST) with the Cisco 3800 Series Routers. SRST provides high availability with
feature-rich call-processing redundancy in the event connection to the centralized Cisco Unified Communications
Manager is lost. Cisco Unity Express provides integrated branch office messaging capability. Cisco Unified Border
