Page 1 of 20Data SheetCisco 1861 and Cisco 2800, 3800, 2900, 3900,and 3900E Series Integrated Services RouterInteroperability with Cisco Unified CommunicationsManagerCisco® 1861 and Cisco 2800, 3800, 2900, 3900, and 3900E Series IntegratedServices Routers can be deployed as unified communications routers as part of theCisco Unified Communications and Collaboration Solution. New and existingdeployments can benefit by using any of these routers as unified communicationsgateways with Cisco Unified Communications Manager.Cisco 1861 and Cisco 2800, 3800, 2900, 3900, and 3900E Series unified communications routers communicatedirectly with Cisco Unified Communications Manager, allowing for the deployment of unified communicationssolutions that are ideal for small and medium-sized businesses, large enterprises, and service providers that offermanaged network services. The Cisco 1861 and Cisco 2800, 3800, 2900, 3900, and 3900E Series Routers providea highly flexible and scalable solution for small and medium-sized branch and regional offices.The Cisco 1861 and Cisco 2800, 3800, 2900, 3900, and 3900E Series unified communications routers support awide range of packet telephony-based voice interfaces and signaling protocols within the industry, providingconnectivity support for more than 90 percent of the world’s private branch exchanges (PBXs) and public-switched-telephone-network (PSTN) connection points. Signaling support includes T1/E1 Primary Rate Interface (PRI), T1channel associated signaling (CAS), E1-R2, T1/E1 QSIG protocol, T1 Feature Group D (FGD), Basic RateInterface (BRI), foreign exchange office (FXO), ear and mouth (E&M), and foreign exchange station (FXS). Youcan configure these unified communications routers to support from 2 to 720 voice channels. Additionally, you canuse these unified communications routers to terminate Session Initiation Protocol (SIP) trunking into the enterpriseor branch office by enabling the Cisco Unified Border Element features. Additional details are available in the CiscoUnified Border Element data sheet.As your enterprise seeks to deploy an expanding list of unified communications applications and services, Cisco1861 and Cisco 2800, 3800, 2900, 3900, and 3900E Series unified communications routers - interoperating withCisco Unified Communications Manager - can provide a solution that will grow with your changing needs.Interoperability Using SIP, H.323, or MGCPThe unified communications routers can communicate with the Cisco Unified Communications Manager usingSession Initiation Protocol (SIP), H.323, or Media Gateway Control Protocol (MGCP):● In SIP and H.323 mode, the unified communications routers communicate with Cisco UnifiedCommunications Manager as intelligent gateway devices.● In MGCP mode, these routers operate as stateless clients, giving Cisco Unified Communications Managerfull control. Dial plans are configured centrally in Cisco Unified Communications Manager. Then you canautomatically configure voice-gateway routers by downloading XML files.
