Unified Communications Gateways
Cisco Unified Border Element
Cisco Unified Border Element (Cisco UBE) is a session border controller that provides the necessary
services for interconnecting independent Unified Communications networks securely, flexibly, and
reliably. Media packets can flow either through the gateway (thus hiding the networks from each other)
or around the border element, if so configured. The Cisco UBE is typically used to connect enterprise
networks to service provider SIP trunks, or to interconnect different nodes in an enterprise network
where protocol or feature incompatibilities exist, or where extra secure demarcation between segments
of the network is needed.
The Cisco Unified Border Element provides the following network-to-network interconnect capabilities:
• Session Management: Real-time session setup and tear-down services, call admission control,
ensuring QoS, routing of calls if an error occurs, statistics, and billing.
• Interworking: H.323 and SIP protocol conversion; SIP normalization; DTMF conversion,
transcoding, codec filtering
• Demarcation: Point of fault isolation, topology hiding, establishing and maintaining network
borders, gathering statistics, and billing information on each network segment separately
• Security: Provides interworking between encrypted and non-encrypted network segment, SIP
registration services, DOS protection, authentication services, and toll fraud protection on H.323 or
SIP trunks.

Unified Messaging Gateway
The Cisco Unified Messaging Gateway provides an open and secure method of intelligently routing
messages and exchanging subscriber and directory information within a unified messaging network. It
acts as the central hub in a network of Cisco unified messaging solutions and third-party gateways that
interface with older voicemail systems.
Unified Messaging Gateway is ideal for companies that need the following key features:
• Scales the unified messaging network as required for branch-office customers and larger distributed
enterprises
• Simplifies configuration tasks and centralize voicemail system management
• Transparently integrates Cisco Unified Communications solutions into existing voicemail
installations
• Integrates small to large-scale unified messaging deployments that consist of more than five Cisco
Unity Express systems.
• Integrates up to 10,000 mixed Cisco Unity Express, Cisco Unity, and Cisco Unity Connection
systems.
