|Headquarters||San Mateo, CA|
IntelePeer is a privately held company based in San Mateo, California, and is a leading provider of business communications, cloud contact center, enterprise voice services, and SIP trunking.
IntelePeer was founded as VoEX, Inc. in 2003 to provide core network VoIP services to large communications services providers, universities, large enterprises and VoIP applications developers. The company was originally based in Grand Rapids, Michigan.
In October 2006, the company introduced its SuperRegistry, which combines interconnection call signaling and media translation, and ENUM Telephone number mapping registry capabilities to allow peering partners who participated in the SuperRegistry to complete calls with each other through direct digital connections to reduce long distance and international call expenses for customers.
VoEX changed its name to IntelePeer, Inc. in September 2007.
In September 2008, IntelePeer launched its AppWorx communications-enabling application development environment offering an application programming interface (API) based on Web standards like PHP and REST to help service providers and application developers to voice-enable their applications.
In November 2008, IntelePeer completed a series C round of financing for $18 million. The financing was led by new investor VantagePoint Venture Partners of San Bruno, California, with participation by existing investors.
In October 2015 IntelePeer acquired Advantone, a cloud contact center company based in Plantation, Florida. IntelePeer added Advantone's contact center suite to its product line, creating the Atmosphere cloud communications platform. 
In 2016, IntelePeer announced its partnership with Cisco to become the first PSTN provider for Cisco's Spark and Meraki products.
IntelePeer offers cloud-based communications services including SIP trunking solutions for enterprises and contact centers adopting unified communications systems. The company's cloud computing technologies let users communicate via voice, videoconferencing, text, and rich media on whatever device they prefer to use.
