The Dialogic Corporation is a worldwide telecom equipment supplier, serving both enterprise and service provider markets. Dialogic's broad product range incorporates media gateways, media servers, signalling gateways and media boards, and embraces both traditional TDM technology and VoIP/SIP.

Brief History

Dialogic was formerly known as Eicon Networks, and took on the name Dialogic in 2006 when it bought the Media & Signalling Division of Intel (this division was known as 'Dialogic' prior to its acquisition by Intel in 1999). The combined Eicon/Intel-Dialogic chose the name Dialogic, as it was still a strong worldwide brandname in the media board space. The Media & Signalling business itself contained acquisitions VTG (media gateways) and Datakinetics (signalling/SS7) that were not part of the original Dialogic from 1999. These are now integrated parts of the new Dialogic.

In 2007, Dialogic bought competitor Cantata, itself a combination of Brooktrout (famous for Fax technology), Excel Switching (operator gateways and service platforms) and Snowshore (IP media server). In early 2008, Dialogic bought Open Media Labs, an expert in video codec technology, which now operates as the Dialogic Media Labs division, supplying advanced video technology to Dialogic. The close of 2008 brought another acquisition, this time NMS (Natural Micro Systems), another competitor in the media server/gateway/board business.

May 2010 saw Dialogic announce a merger with Veraz Networks, also in the telecom equipment space and with a service-provider focus. The resulting company would be known as Dialogic, headed by exisiting Dialogic CEO Nick Jensen.


Today the Dialogic Corporation offers a combination and evolution of all of the product families from the constituent companies including:

In addition, Dialogic still serves a number of legacy markets such as ISDN and X.25. More detail is available here on Dialogic Board Families.

Project DiaStar is an open source project sponsored by Dialogic that makes a lot of Dialogic functionality available to open source platforms, notably Asterisk and Freeswitch. It is based around the open Woomera driver, allowing media and signalling offload to another server. DiaStar encompasses not just VoIP but also video and SS7 signalling.

Dialogic Media Labs (or DML) provides video technology to Dialogic, notably H.264 codec and rate control algorithms used in Dialogic's own video-enabled products including PowerMedia™ HMP. DML also licenses technology to third parties, such as quality of experience (QoE) technology for the growing IP video market.
