Dialogic 1000 and 2000 Media Gateway Series - Link

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 ServerThe 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.
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

This white paper compares the two principal options for implementing fax in a VoIP network today: Fax-Relay (T.38) and Fax Pass-Through (G.711) and concludes that Fax Relay is superior.

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.
