Telogy Networks

Telogy Networks was one of the first companies to deliver software solutions enabling voice over IP (VoIP) networks. Founded in 1989 and headquartered in Germantown, Maryland, the company built the Golden Gateway telephony software and DSP-resident voice/fax media processing stacks that were embedded into carrier and enterprise gateway equipment. Backed by Lightspeed Venture Partners (invested 1997), ABS Ventures, Ameritech Development, Catalyst Venture Partners, and Novak Biddle Venture Partners, Telogy Networks was acquired by Texas Instruments in 1999 for roughly $457 million, where its VoIP media-gateway software became the basis of TI's telephony DSP product line. Telogy no longer operates as an independent entity and publishes no developer portal, public API, or SDK. This record is retained in the API Evangelist network as a historical VC-portfolio company profile.

Telogy Networks is profiled on the APIs.io network. Tagged areas include Company, Telecommunications, Voice over IP, VoIP, and Media Gateway.
