Product Overview

Cisco® Unified Border Element, our session border controller, allows control of SIP services with registered external entities, most commonly service providers that offer VoIP services based on SIP or H323 protocols. This software is available for licensing on the Cisco IOS® Software. It runs on many of our enterprise routers, but is also available for licensing as a software load for a virtual container. This document lists the specific routers on which CUBE is supported, including the ASR 1000, the ISR 4000, the ISR G2, and several models of the 800 fixed‑configuration routers. The virtualized CUBE, or vCUBE, runs in an ESXi virtual container.

You can do a lot at the edge of your network with Cisco Unified Border Element (CUBE). You can make the transition from time-division multiplexing (TDM) to Session Initiation Protocol (SIP) trunking easier, tailoring the architecture to meet your network and business needs. You can significantly decrease toll charges for web conferencing. You can implement call recording based on various call recording mechanisms. You can stop telephony denial-of-service attacks at your gateway. If outbound calls from your contact center don’t connect with a person, you can keep those calls from cluttering up agents’ time. You can more easily access cloud collaboration services, including voice and video media, and providers can offer these services more cost-effectively. Cisco Unified Border Element supports all these applications and more.

Part of the Cisco Collaboration edge architecture portfolio, the Cisco Unified Border Element (CUBE) is an enterprise-class session border controller that connects large, midsize, and small business unified communications networks to the IP public switched telephone network (PSTN). In addition to session border control, CUBE has many other capabilities, including simple and cost-efficient collaboration beyond the enterprise firewall. Collectively these functions give you unprecedented flexibility for architecting your network.

CUBE use cases include:

   IP PSTN connectivity with SIP Trunking (with or without TDM backup)

   Cisco WebEx® Cloud Connected Audio (CCA)

   Voice and video recording

   Call-center and interactive-voice-response (IVR) solutions

   Voice policy

   Cloud connectivity solutions for Cisco and third-party hosted call control

   VPN-less SIP phone proxy registration to hosted SIP-based call control

   Business-to-business telepresence, voice, and video interconnect.

Each of these use cases is described in more detail in the following sections.

IP PSTN Connectivity with SIP Trunking

The benefits of unified communications and collaboration services will continue to grow as voice, video, and mobile services become more pervasive elements of integrated collaboration solutions. However, these enhancements will be available only if you deploy end-to-end real-time IP communications for both inter- and intracompany voice and video services based on SIP. This deployment requires transitioning your service provider network interconnect from TDM circuits to SIP trunking.

The SBC has become a critical network component for scaling and securing unified communications networks. The SBC makes it possible to expand end-to-end IP connectivity for real-time voice and video through service provider SIP trunks or through a secure SIP session over the Internet to directly connect two enterprise networks.

Cisco Unified Border Element supports the transition to SIP trunking by enabling Cisco or third-party IP call and session control to connect to and interoperate with service provider SIP trunk services. It terminates and reoriginates both signaling (H.323 and SIP) and media streams (Real-Time Transport Protocol [RTP] and Real‑Time Control Protocol [RTCP]) to provide secure border interconnection services between IP networks. Using this solution, Cisco customers can save on their current network services, simplify their network architectures, and position their networks for ongoing enhancements in collaboration services.

You can deploy CUBE virtually on Cisco Unified Computing System (Cisco UCS®) servers, or as an integrated Cisco IOS Software application, it runs on a broad range of Cisco router platforms. These routers include the Cisco 800, 2900, 3900, and 4000 Series Integrated Services Routers (ISRs) as well as the Cisco ASR 1000 Series Aggregation Services Routers. The breadth of Cisco router platforms that support the CUBE feature license means that it provides unsurpassed price and performance scalability compared to other enterprise SBCs. This scalability translates into network design flexibility for enterprise, midsize, and small businesses. It also means operational efficiencies and a broader serviceable market for service providers that include CUBE as part of their SIP trunk managed or hosted services.

CUBE performs the following functions between the enterprise and service provider networks:

   Session control: The capability to offer flexible trunk routing, Call Admission Control (quality of service [QoS]), and resiliency and call accounting for the SIP sessions processed by the SBC

   Interworking: The capability to interconnect different signaling methods and media encoding variants for both voice and video sessions

   Demarcation: The capability to act as a distinct demarcation point between two networks for address and port translation and to facilitate troubleshooting

   Security: The capability to intelligently allow or disallow real-time traffic between networks, and to encrypt the real-time traffic as appropriate for the application

Flexible SIP interconnect: As a Cisco IOS Software feature set that runs on a broad range of Cisco routers (complete list in Table 2 below), CUBE enables great flexibility in how you design your SIP trunk network. Of course, this means you can now use existing Cisco routers as a CUBE platform. As a result you can deploy CUBE in centralized, distributed, or hybrid (combination of centralized and distributed) SIP architectures. This flexibility is invaluable as collaboration use cases, such as conferencing, video, and mobility, evolve and place increased demands on the enterprise network. Many service providers have recognized their customers’ need to adapt and now offer multilocation SIP trunk pooling services. You can take advantage of these service offerings because of the unsurpassed SBC price and performance flexibility that CUBE provides.

For SIP network deployments that require a centralized architecture, you can deploy a CUBE Cluster: a highly scalable, highly available configuration that is created when CUBE is used with Cisco Unified SIP Proxy (Cisco USP), which can support up to 64,000 concurrent sessions in a single cluster.

Simplified TDM-to-SIP migration: For most enterprises, the transition from TDM trunk services to SIP trunk services requires careful planning because this transition must be achieved while maintaining a functional voice network. This planning involves, among other things, addressing the service provider requirement for number portability and the IT requirement for dial-plan revisions. CUBE can simplify this transition, particularly for Cisco customers who already use the Cisco TDM Gateway on the Cisco 2900, 3900, and 4000 Series ISRs. You can easily upgrade these gateway platforms, without requiring any additional hardware to support the CUBE feature license. Because they can concurrently support SIP trunking and TDM trunking, you can transition your voice network to SIP trunking while retaining the existing TDM gateway functions. Furthermore, this can be achieved without making any changes to the centralized dial plan of your organization. As you become familiar and confident with SIP trunking, you can phase out the TDM Gateway function, or retain it as a high-availability redundant network strategy.

Cisco WebEx Cloud Connected Audio

Cisco WebEx Cloud Connected Audio (CCA) is a cost-effective audio conferencing solution for Cisco WebEx meetings and is enabled by CUBE. It extends the functions of Cisco Unified Communications Manager and incorporates on-premises equipment to connect your organization to a Cisco WebEx Cloud data center through dedicated peering connections. CUBE provides the high-capacity SIP media connectivity to the WebEx® cloud to replace the TDM audio connection. It allows SIP sessions from all enterprise sites to connect to the Cisco WebEx cloud and avoids media hairpinning to provide the most efficient network usage.

Voice and Video Recording

CUBE supports voice-recording solutions by providing various mechanisms to invoke media forking on a per-call basis. One method, SIP-based and derived from the SIPREC standardization process, sends a forked SIP invite to the target recording application server, which can either accept or reject the call.

An alternative method is an HTTP-based application programming interface (API) that allows Cisco Unified Communication Manager (CUCM), starting with version 10.0, to instruct CUBE to perform the media forking for each specific call session, and can toggle the media forking through the duration of an active call.

Call-Center and IVR Solutions

CUBE provides numerous features to improve the performance of your enterprise call center. For example, it supports midcall codec renegotiation, with either internal transcoding or external endpoints, to allow different codec support for IVR versus live agent communication. CUBE also supports SIP-based Call Progress Analysis for outbound call-center solutions, thereby enabling an entirely SIP-based call center environment for both inbound and outbound customer contact functions. CUBE, as a gateway function, is also closely integrated with IVR functions, because it runs concurrently on the Integrated Services Routers Generation 2 (ISR G2) router with the Cisco IOS Software-based VoiceXML.

Voice Policy

CUBE, as part of its complete SBC security function, supports policy-led evaluation of phone calls. This capability is becoming increasingly critical as incidents of telephony denial of service (TDoS) attacks are more prevalent, as evidenced by the formal public warnings of such attacks being given by the U.S. Federal Bureau of Investigation (FBI) and Department of Homeland Security (DHS). CUBE enables highly flexible and granular voice-policy solutions to identify specific patterns of calling activity from either internal users (employees) or external callers and to take appropriate action when those patterns occur, including call termination, call redirection, and call recording. This call pattern recognition helps ensure that the enterprise voice network is not disrupted by external callers with malicious intentions, but rather is used to support the strategic communications activities of the business, as intended.

Cloud Connectivity Solutions for Third-Party Hosted Call Control

Many service providers offer hosted call-control services to their small customers based on cloud-based private-branch-exchange (PBX) software such as BroadSoft. Using the NANOCUBE licensing (refer to the “CUBE Licensing Options” section later in this document), Cisco 800 Series ISRs, part of the Cisco Integrated Services Routers - Generation 2 (ISR-G2) portfolio, can be included as part of these hosted call-control services to perform gateway functions at the customer premises, such as registration pass-through, voice quality metrics, and 911 preemption.

Business-to-Business Telepresence, Voice, and Video Interconnect

CUBE provides secure connectivity for Cisco TelePresence® deployments over SIP, either on a point-to-point basis over the Internet between two private enterprise networks or from a private enterprise network to a telepresence service provider.

CUBE Licensing Options

CUBE can be licensed according to the following three different licensing options:

   Standard CUBE licensing: Standard licensing is used for CUBE licensing with all modular Cisco ISR and Cisco ASR 1000 Series platforms to deliver the full range of CUBE functions, but without high availability. This license is per-session, and a session is defined as a two-way call through CUBE regardless of the number of media sessions involved in that call (that is, a video call with four media lines or sessions or an audio call with two media lines or sessions).

   Redundant CUBE licensing: Redundant licensing is used for CUBE with all modular Cisco ISR and Cisco ASR 1000 platforms to deliver the full range of CUBE functions, including high availability with call preservation between an active and standby CUBE. This licensing option also allows for license transfer between two geographically distributed CUBE platforms, as in the scenario of a dual-data-center deployment strategy, where CUBE service redundancy without call preservation is satisfactory.

   NANOCUBE licensing: NANOCUBE licensing is used only for Cisco 800 Series ISR and Cisco Service Provider Integrated Access Device (SP-IAD) platforms typically as part of a third-party (not based on Cisco Hosted Collaboration Solution [HCS]) cloud-hosted call-control solution. This licensing option also supports other CUBE features, except to the extent that such features require additional hardware platform support, such as digital signal processors (DSPs) for transcoding.

More information about these licensing options can be obtained in the CUBE Ordering Guide available at:
http://www.cisco.com/go/cube.

1.     Select a Cisco router based on performance requirements (refer to Table 6).

2.     Select a Cisco IOS Software image with Cisco Unified Border Element (CUBE) feature support (all IP Voice and later images support some components of the CUBE).

Summary

Organizations large and small are realizing the value of SIP-based communication. The Cisco session border controller, CUBE, is helping these organizations take advantage of service providers’ SIP services by providing voice and video connectivity for both trunk and line-side service offerings. As such, CUBE is ideal for businesses of all sizes; it cost-effectively supports a variety of SIP services, whether with premises-based call control or hosted call control, with the added benefit that CUBE uses the customer’s existing investment in Cisco routers.
