Dialogic® 2000 Media Gateway Series (DMG2000 Gateways) is a suite of touring applications that seamlessly merge traditional PSTN technology with IP networks.
The Dialogic® 2000 Media Gateway Series (DMG2000 Gateways) is a suite of touring applications that seamlessly merge traditional PSTN technology with IP networks. These cost-effective solutions enable the development of separate voice and data networks and provide new and differentiated communication services. Without radical, disruptive, expensive upgrades to existing PBX equipment, service providers and enterprises can realize the benefits of converged voice and data network with its gateways.
Features & Benefits:
International communication between PBXs and various IP conferences is carried out
Available communications between networked networks and SIP-based communication devices such as IP phones, unified messaging applications, and IP phones
Available in single, inch and quad density T1/E1 rack mount appliances
Offers a range of products densities to fit the needs of a variety of applications and business sizes
Works great with a number of popular PBX designers including Avaya, Mitel, NEC, Nortel, and Siemens
Protection investment in legacy telecommunications equipment and allows phased migration to IP
Support for IP load balancing and IP fault tolerance
Disability Applicability (TDM-to-IP) call to round-robin medzi available media servers and automatically routes calls away from unresponsive media or proxy servers
Additional services on CAS, QSIG, Euro ISDN, NI2, DMS100, 5ESS protocols, enabling call transfer, call hold, MWI, and call party information
Help retain key supplementary services in the new IP environment
Seamless interoperability with Dialogic® Host Media Processing (HMP) Software
Provides an option for customers to build advanced 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 including context-sensitive Help
Easy to install, configure, debug, and maintain
IP Security Features include TLS, SRTP, and HTTPS
Additional secure communications for SIP messages via TLS, for stream media streaming SRTP, and for websites via HTTPS
The DMG2000 Gateways can be installed and configured “plug and play,” reducing the total cost of ownership. Operations, Administration, and Maintenance (OA&M) properties such as network alarm events, remote management enabled by a userfriendly web interface along advanced diagnostics and administration tools make the installation and maintenance of these appliances quick and easy.
The DMG2000 Gateways were considered a necessary and ideal solution for customers interested in developing a variety of applications such as PBX extension, remote office connectivity, long-distance consolidation, call centers, and IP media servers. Available in 19 different standard chassis mounting gear, these devices are also suitable for service providers who provide IP-PBX, IP Centrex, and advanced data servers.
Save Time, Money – and Existing PBX Equipment
In the large plan of enterprises already have a union of PBX equipment, established in their indicators. They take part in the movement of their communications payments when performing VoIP-solution, and want to save their investment in legacy equipment. Therefore, these enterprises have all sorts of PBX equipment bases, the solution designers need a product that will help the address this wide customer
base with a single, simple solution.
The DMG2000 Gateways should be tested for interoperability with eligible PBXs from vendors such as Alcatel, Avaya, Mitel, NEC, Nortel, and Siemens. These tests years designers' decisions focused on customer applications rather than integration efforts with legacy PBXs. By providing IP connectivity, the DMG2000 Gateways support key supplementary services such as call transfer, call forwarding, call hold, message waiting indicator (MWI), and call party information on most T-1/E-1 protocols including CAS, QSIG, Euro ISDN, NI2, DMS100, and 5ESS, enabling customers to retain application-critical PBX functionality in the emerging VoIP space.
Advanced Voice Features Provide Superior Caller Experience
The excellent features of the DMG2000 Gateways can help establish reliable, high-quality VoIP applications. The Gateways provide the interoperability needed for high-quality streaming medium with a wide variety of industry-standard IP endpoints by supporting advanced coders including:
- G.711 (packet size 10 ms, 20 ms, and 30 ms)
- G.723.1
- G.729ab
The DMG2000 Gateways has QoS features, including Type of Service (TOS)/IP precedence, and DiffServ, providing a low-latency, high-level reliability system for reliable road transport across entire networks. When resolved, communications support progressive transmission of progress on all channels.
