Overview:
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.
The DMG1000 Gateways provide a simple, cost-effective 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).
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.
Applications
- Centralized VoIP and FoIP application servers, including IP-based voice mail and unified messaging
- IVR and announcements
- IP PBX
- VoIP extension to branch offices
- Contact centers
Functional Description
The DMG1000 Gateways each contain eight digital PBX emulation interfaces and a 10/100 Base-T 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, cost-effective 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
Call Routing
The DMG1000 Gateways route calls from the switched network to a VoIP destination on the IP network. Conversely, the DMG1000 Gateways route calls from the IP network through a switch port to a destination telephone number on the switched network. The DMG1000 Gateways support the following call routing options:
- User-configurable list of VoIP servers
- IP load balancing
- IP fault tolerance
- TDM-to-TDM
