Detailed Overview

OMP 3.6 - Videoconference feature.

Now with OMP, you can rely on professional video-conference foundations to build up your up-to date multimedia conference application. Each user might have his own view, adapted to his audio/video capacities and screen resolution. Some advanced features as image and text overlay can be triggered together with the videoconference sessions.

Open Standards and the Web Model

The Voxpilot Open Media Platform architecture leverages W3C and IETF openstandards, which revolutionize the way in which voice services are deployed, bringing IVR from the old world of proprietary platforms into the Internet age. These include certified VoiceXML 2.0 compliance as well as support for SSML, SRGS, SISR and CCXML. Voxpilot employs the Media Resource Control Protocol (MRCP) for integrating leading media resources such as speech recognition and speech synthesis engines.

VoiceXML introduces the Web application development and deployment model to the world of telephony-based interactive services. Existing investments in Web infrastructure such as Web servers, application server-based business logic, and databases can be leveraged to facilitate rapid development of new and innovative applications and services. Moreover, the Web model allows companies to exploit their existing Web expertise and apply it to revenue generating, telephony-based services.

IP Convergence

The unique combination of VolP and PSTN interfaces supported by the Voxpilot OMP makes it ideally positioned to support the migration from traditional telephony networks to next generation "all-IP" network architectures such as the IP Multimedia Subsystem (lMS).

The Third Generation Partnership Project (3GPP/3GPP2) introduced the IMS architecture as part of their vision to drive convergence of the cellular and lnternetworlds by seamlessly integrating voice, data, and multimedia services on the same network. Fueled largely by the fact that IMS is access network independent and hence ideal for wireless-wirelineconvergence, it is fast becoming the leading reference architecture for next generation networks. lt will allow deployment of interactive TV  streaming of multimedia files, and IVVR services on any lMScompliant network thereby safeguarding platform investment.

IMS leverages open standard IETF protocols with SIP notably providing the core signaling protocol. Through SIP the Voxpilot OMP integrates easily into IMS network architectures providing a rich media resource function (MRF) feature set to SIP Application Servers. With over 6 years experience developing and deploying VolP technologies, Voxpilot is committed to supporting next generation all-lPnetwork architectures.

Speech Engine Agnostic

The Voxpilot Open Media Platform supports the best-of-breed speech recognition and speech synthesis engines from vendors such as Scansoft, Nuance, Telisma, Loquendo, and Acapela. Engines from different vendors may even be configured in the same deployment. Customers have the flexibility to choose their preferred speech engine vendor based on their specific requirements for language support and features. With the advent of open protocols such as MRCP, customers avoid "vendor lock-in".

Engineered for Video

The availability of new media features, driven by improved terminal and network capabilities, is enabling the delivery of new and exciting video applications and multimedia services. In addition to supporting rich audio processing capabilities such as speech synthesis and speech recognition, the Voxpilot Open Media Platform is engineered to support video applications and multimedia services both in currently deployed 3G networks (3G-324M) and directly in IP-based network architectures such as IMS.

VoiceXML, while originally developed for speech and DTMF interactive services, is a natural paradigm for delivering rich, video-enabled services. Video is simply another media channel in a human-machine dialog and, to that end, standard functionality such as video playback, record, and data push to web servers is possible today through standard VoiceXML. Indeed, the combination of rich audio and video capabilities offered through a single Web-based service creation approach such as VoiceXML, results in an exceptionally powerful multimedia service delivery paradigm that goes far beyond what has been available up to now.

Carrier-Grade Quality

Voxpilot'splatform technology has had many years of deployments executing applications written by thousands of developers. The result is a robust, carrier-grade product with proven scalability. Employing  SIP, MRCP, HTTP and SNMP protocols in the platform design facilitates scalable, load-balanced, and maintainable clusters of Call Server, VoiceXML Media Server and speech engine resources to be deployed in a reliable fashion.

As an active member of the standards community, Voxpilot was one of the firstcompanies to achieve VoiceXML Forum Platform Certification, which involved independent and rigorous testing of all VoiceXML 2.0 features. Voxpilot is both a contributor and editor of W3C and IETF specifications and committed to the development and evolution of open standards. It also promotes advancements like video processing with VoiceXML to be part of the upcoming VoiceXML 3.0 standard.

The Voxpilot OMP leverages a leading SIP stack to provide high quality, interoperable, and scalable SlPconnectivity to the Call Server and VoiceXML Media Server. It supports Red Hat Enterprise Linux and Microsoft Windows operating systems and runs on standard lntelhardware. The Platform also addresses both low-end and high-end densities, supporting configurations ranging from 2 ports up to 480 ports per Server.

Multi-Application Platform

The Voxpilot Open Media Platform can support a wide range of VoiceXML powered self-service applications executing on the Web tier, including:

• Directory assistance
• Conferencing
• Voice and video mail
• Video interactive services
• Call centre self-service and intelligent routing
• Voice service outsourcing / hosting
• Voice portal

 

Voxpilot VoiceXML Media Server

The SlP-based VoiceXML Media Server provides a certified VoiceXML 2.0 and VoiceXML 2.1 compliant interpreter and SSML 1.0 processor. It integrates the requisite host-based media processing functions including audio/video announcement and recording, DTMF detection and generation {RFC 2833), SRGS DTMF recognition, and media forking. ltemploys MRCP to provide seamless control of speech media resources for performing speech recognition and speech synthesis actions.

The VoiceXML Media Server allows developers to create advanced interactive video services using standard VoiceXML by leveraging the 3GP multimedia file container format and content from RTSP streaming servers. ltcan interoperate directly with the Call Server for 3G-324M services or with any standard SIP-based video gateway.

The Voxpilot VoiceXML lnterpreteris implemented natively for optimum performance, and has been designed to be highly robust and scalable and includes an active health monitoring system for detecting and alerting to potential problems. The Voxpilot SSML Processor supports all leading TTS engines and the Voxpilot AudioEnginefor streaming, caching and transcodinglocal and remote audio files.

The VoiceXML Media Server includes numerous configuration parameters to allow for effective customisation and extension modules can be easily plugged in for interfacing directly with external systems. Real-time control and monitoring is achieved through Web consoles.

Voxpilot Call Server

The Voxpilot Call Server provides rich programmatic call control and gateway features to the Voxpilot Open Media Platform. It supports SS7 call control protocols such as ISUP  in addition to lNprotocols such as INAP. The Call Server also readily supports other telecommunications protocols including ISDN and 3G-324M video.

In traditional PSTN or PLMN networks, the Call Server can interface within the Intelligent Network (lN) as an Intelligent Peripheral (lP) or a Service Control Point (SCP) via the INAP protocols. The Call Server simultaneously addresses next-generation telephony requirements by fully supporting the SIP/RTP protocols for VolP and providing signaling and media gateway functionality between IP and circuit-switched networks.

The Call Server may be programmed via CCXML or Orateurscripts (an event-driven programming language). Extensions and libraries may be created and added to interface with external systems. It is integrated with industry leading CTI environments by means of specific extension packages. The Call Server can be deployed with hardware-based DSPs for media processing and signaling or all software in an IP deployment with Host Media Processing.
