Datasheet Media Gateway ® Dialogic 2000 Media Gateway Series ® The Dialogic 2000 Media Gateway Series (DMG2000 Gateways) is a set of turnkey appliances that seamlessly merge traditional PSTN technology with IP networks. These economical gateways help consolidate typically separate voice and data networks and provide new and differentiated communication services. Without making radical, disruptive, and expensive upgrades to existing PBX equipment, service providers and enterprises can realize the benefits of a converged voice and data network with these gateways. Features Benefits Provides an interconnect between legacy PBXs and various Enables communication between a circuit-switched telephony IP endpoints network and Session Initiated Protocol (SIP) compatible remote devices such as IP voice mail, unified messaging applications, and IP phones Available in single, dual, and quad density T1/E1 rack mount Offers a range of product densities to fit the needs of a variety appliances of applications and business sizes Compatible with a variety of popular PBX manufacturers Protects investment in legacy telecommunications equipment including Avaya, Mitel, NEC, Nortel, and Siemens and allows a phased migration to IP Support for IP load balancing and IP fault tolerance Allows the ability for inbound (TDM-to-IP) calls to round-robin between available media servers and automatically routes calls away from unresponsive media or proxy servers Supports supplementary services on CAS, QSIG, Euro ISDN, Helps retain key supplementary services in the new NI2, DMS100, 5ESS protocols, enabling call transfer, call IP environment hold, MWI, and call party information ® Seamless interoperability with Dialogic Host Media Provides the option for customers to build enhanced Processing (HMP) Software applications on top of base gateway and PBX functions, and make those applications available on legacy handsets Supports configuration via serial, telnet, and a web browser Easy to install, configure, debug, and maintain including context-sensitive Help IP security features include TLS, SRTP, and HTTPS Enables secure communications for SIP messages via TLS, for media stream via SRTP, and for web interface via HTTPS Applications • Centralized VoIP and FoIP applications servers, including IP-based voice mail and unified messaging • Interactive voice response (IVR) and announcements • IP PBX • Voice over Internet Protocol (VoIP) extension to branch offices • Contact centers ® Datasheet Dialogic 2000 Media Gateway Series The DMG2000 Gateways can be installed and In addition to providing IP connectivity, the DMG2000 Gateways support key supplementary services such as configured “plug and play,” reducing the total cost call transfer, call forwarding, call hold, message waiting of ownership. Operations, Administration, and indicator (MWI), and call party information on most Maintenance (OA&M) features such as network T-1/E-1 protocols including CAS, QSIG, Euro ISDN, alarm events, remote management enabled by a user- NI2, DMS100, and 5ESS, enabling customers to retain friendly web interface along with advanced diagnostics application-critical PBX functionality in the new VoIP and administration tools make the installation and environment. maintenance of these appliances quick and easy. The cost of the DMG2000 Gateways makes them a Advanced Voice Features Provide Superior unique and ideal solution for enterprises interested in Caller Experience deploying a variety of applications such as PBX extension, The extensive features of the DMG2000 Gateways can remote office connectivity, long-distance consolidation, help build a reliable, high-quality VoIP application. call centers, and IP media servers. Available in a 19-inch The gateways provide the interoperability needed for standard rack mountable chassis, these appliances are high-quality media streaming with a wide variety of also ideal for service providers offering hosted IP-PBX, IP industry-standard IP endpoints by supporting advanced Centrex, and enhanced messaging servers. coders including: • G.711 (packet size 10 ms, 20 ms, and 30 ms) Save Time, Money — and Existing PBX • G.723.1 Equipment A large base of enterprises today have legacy PBX • G.729ab equipment installed in their premises.

The DMG2000 Gateways have been tested for The DMG2000 Gateways have QoS features, including interoperability with legacy PBXs from vendors such type of service (TOS)/IP precedence, and DiffServ, as Alcatel, Avaya, Mitel, NEC, Nortel, and Siemens. providing a low-latency, high-reliability path for sensitive This testing lets solution providers focus on customer voice traffic through today’s networks. In addition, the applications rather than integration efforts with legacy gateways support advanced call progress analysis on all PBXs. channels. 2 ® Dialogic 2000 Media Gateway Series Datasheet LAN/WAN SIP Telephone Sets Gatekeeper SIP Base Station ® Dialogic 2000 Media Gateway Series ® Desktop with Microsoft SIP Application Server NetMeeting or Other (UM, CC, IVR, etc.) Legacy PBX Soft Client Figure 1. Bridge the Gap Between PSTN and IP End Points Configurations The DMG2000 Gateways provide a cost-effective way to connect various IP end points to the circuit-switched network (see Figure 1), eliminating the need to swap out legacy PBXs and helping to protect telecom investment. ® The DMG2000 Gateways along with Dialogic HMP Software support the development of cost-effective IP media servers accessible from both PSTN and IP networks (see Figure 2). IP media servers can provide a central and efficient messaging server in existing Time Division Multiplex (TDM) voice infrastructures by servicing remote locations via an IP network. 3 ® Datasheet Dialogic 2000 Media Gateway Series LAN ® Nortel Centralized HMP Brussels Meridian Media Server SIP Phone WAN ® Dialogic 1000 Media Gateway Series (PBX/Analog) Legacy Phones SIP ® Seimens Munich Hicom ® Dialogic 2000 Media Gateway Series ® Dialogic 1000 Media Gateway Series (PBX/Analog) Legacy Phones ® Ericsson Stockholm Legacy Phones MD110 ® Avaya G3 PBX PSTN ® Dialogic 1000 Media Gateway Series (PBX/Analog) Legacy Phones Headquarters Remote Offices Figure 2. Converged IP Media Server Architecture Media gateways help service providers and enterprises offer cost-saving voice, data, and multimedia convergence services. One such solution is an application for telecommuters. The number of employees working from home on a permanent or periodic basis continues to rise. These employees need full access to company voice and data services. By installing a DMG2000 Gateway (see Figure 3), employees working from home can have the same telephony experience as their counterparts in the corporate office. They can make and receive calls and access other features such as voice mail from home, just as if they were in the office. Their office extension can be “bridged” onto a gateway port so that their “phone” rings, no matter where they are working. This enhances productivity, reduces costs, and improves both customer and employee satisfaction. 4 ® Dialogic 2000 Media Gateway Series Datasheet Corporate Office Home Office Router Voice Mail Laptop with VPN Software VPN Server Switch and Softphone Email Server ® or Microsoft File Server NetMeeting VPN Optional Home SIP Proxy Router DSL or Cable Modem Headset or USB Handset ® T1/E1 PBX Dialogic 2000 Media Gateway Series Figure 3. Next-generation Application Solutions — Telecommuting The DMG2000 Gateway is able to address SIP trunking, PSTN toll bypass, and other access gateway applications. The gateway provides TDM-to-TDM routing as well as the traditional SIP-to-TDM and TDM-to-SIP routing. With this routing addition, as well as the addition of failover relays for direct TDM-to-TDM connectivity in case of power failures, or IP network issues, the gateway provides a survivable telephony connection (see Figure 4).
