Overview
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.
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.

| This application note describes a method to configure the Dialogic 1000 Media Gateway Series or Dialogic 2000 Media Gateway Series and the Asterisk IP-PBX Server software to inter-operate without connecting phone lines into your server running Asterisk. Configuration files that need to be modified are available for download. | Using a Dialogic Media Gateway Series as a PSTN Gateway with an Asterisk IP-PBX Server |
| The Dialogic 1000 Media Gateway Series basic theory and operation is explained in this application note. This includes analog versus digital deployments and serial protocol overview. It provides the theory of operations across the serial link, shows how a typical serial link operates with master/slave gateways, provides the configuration of serial protocol parameters, and discusses the protocol configuration pages for the various call party identification (CPID) modes. | Dialogic 1000 Media Gateway Series Serial CPID Configuration and Timing | |
| A number of private branch exchange/key system unit (PBX/KSU) systems support the sending of call party identification (CPID) information to a destination analog station via in-band dual-tone multifunction (DTMF) digits. PBX/KSU systems refer to these types of analog stations as voice mail interface (VMI) ports. This application note discusses the way in which the Dialogic 1000 Media Gateway Series work with DTMF/CPID digits. | Receiving Analog In-Band CPID with the Dialogic 1000 Media Gateway Series | |

Whitepapers | Although many enterprises are eager to deploy converged voice and data applications and services over IP, they see their legacy PBX systems and upfront costs as roadblocks to the enhanced capabilities that IP would bring. This paper demonstrates that legacy PBX equipment does not have to be replaced for enterprises to begin a phased migration to IP convergence. Dialogic media gateway appliances make the implementation of IP technology in PBX systems possible right now, and with low upfront investment costs. | Choosing a Media Gateway Appliance |
