You can try the Prophecy Platform at no cost, right now, via our free Prophecy download or our free hosted Evolution developer portal.



Voxeo Prophecy SIP Application Server

Voxeo's Prophecy SIP Application Server software is built around the world's most proven Call Control (CCXML) engine, which has routed over 1 billion calls since its first production deployment by Voxeo in January, 2002. CCXML is the industry standard for call control application development, created by the W3C - the same standards body that created the enormously successful HTTP and HTML standards.

The Prophecy SIP Application Server uses CCXML and ENUM to give you unmatched control over your calls. CCXML enables you to intelligently screen, route, transfer, and initiate traditional and SIP calls, and includes support for call-center Computer Telephony Integration (CTI) interfaces from Avaya, Cisco, Nortel, and others. ENUM lets you define data-driven call routing plans using DNS, the most pervasive directory and addressing technology available today.

Voxeo Prophecy SIP Media Server

Voxeo's Prophecy SIP Media Server software delivers a resume even more impressive than that of its SIP call control sibling. Built on the world's most proven Host-based Media Processing (HMP) engine, the Prophecy SIP Media Server has played, recorded, conferenced and signaled its way through 3,000,000,000,000 VoIP packets since 1999. Yes, that's three trillion.

The Prophecy SIP Media Server gives you complete control over those packets with its certified-compliant W3C VoiceXML IVR and speech media application engine and Voxeo's CCXML media extensions. VoiceXML provides features to play prompts and speak synthesized text, record audio, and receive input via touch-tone entry or comfortable speech recognition. CCXML adds to these features with the ability to record or conference any call.

Prophecy is compatible with any speech synthesis or recognition engine supporting the IETF Media Resource Control Protocol (MRCP) standard; is itself a powerful MRCP media and media proxy server; and ships bundled with highly intelligent English language speech recognition and speech synthesis engines. All you need to add is your own media application - or one of the pre-built applications provided by Voxeo's VoiceWorks application partners.
