The Dialogic® 1000 Media Gateway Series (DMG1000 Gateways) allows for a well-planned, phased migration to an IP network, making the gateways a smart solution for enterprises looking to enhance their legacy PBX equipment with new VoIP access and applications. Connected between a PBX or a digital handset and a LAN or WAN, the DMG1000 Gateways convert proprietary digital PBX messages into a format suitable for transmission over standard IP networks.
Features & Benefits
Suitable for small to medium enterprises and easy to install, configure, and maintain, Compatible with a variety of popular PBX manufacturers including Alcatel, Avaya, Ericsson, Fujitsu, Mitel, NEC, Nortel, and Siemens Protects investment in legacy telecommunications equipment and allows a controlled migration to IP technology.
Designed, developed, and tested in Dialogic’s state-of-the-art PBX lab and optimized for use in an Enterprise environment Ideally suited for Enterprise Unified Messaging applications (tested and certified with Microsoft® Exchange Server UM)
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
Seamless interoperability with Dialogic® HMP Software Provides the options for customers to build enhanced applications on top of base gateway and PBX functions
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 Enables secure communications for SIP messages via TLS, for media stream via SRTP, and for web interface via HTTPS
The DMG1000 Gateways each contain eight digital PBX emulation interfaces and a 10/100 BaseT Ethernet connection for connecting to a LAN. An analog loop start unit designed for voice mail and unified messaging applications is also available to connect to PBXs that do not have an appropriate digital interface. The analog loop start unit supports integration via in-band signaling (DTMF or FSK) or serial protocols (SMDI, MCI, and MD-110).
The DMG1000 Gateways provide a simple, costeffective transition to voice and data convergence for enterprises with PBXs. Connected externally, they offer an IP solution that works with current legacy equipment. They support SIP-based applications as well as T.38 for fax transmissions over IP (FoIP).
Gateway unit features include:
Voice over Internet Protocol (VoIP) – Supports SIP per RFC 3261. Uses Real-time Transport Protocol/Real- Time Control Protocol (RTP/RTCP) for delivery of voice over the LAN or WAN
IP security — Supports TLS for SIP messages, SRTP for media stream, and HTTPS for web interface
Enhanced voice processing – Supports a variety of compression algorithms, including G.711 A-law and μ-law, G.723.1, and G.729AB
T.38 Fax over Internet Protocol (FoIP) – Emulation units transcode fax from T.30 fax protocol, supporting V.17, V.21, V.27, and V.29 modulation schemes, to T.38 for transmission over a packet network
Hot swap – Allows gateway units to be added or removed without affecting other gateway units
Web server interface – Each gateway unit is delivered with a web server interface, allowing configuration and software upgrades via a web browser
The DMG1000 Gateways can be used to connect IP telephones to a legacy PBX, integrate network- hosted applications with the PBX, extend the PBX to branch offices, and integrate various voice and call processing capabilities in an enterprise LAN or WAN environment. Using exclusive PBX network interfaces (emulating), these media gateway appliances provide exceptional IP to PBX integration capabilities to protect an investment in legacy telecom equipment.
