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
Configurations:
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.
