The pre-requisites for integrating new voice applications with Portal Server Mobile Access 7.1 Developer's Guide software are:
Voice components of Mobile Access software are certified against the Nuance Voice Platform, which includes a VoiceXML 2.0-compliant voice browser. Because of differences between VoiceXML interpreters, the voice components might need to be ported to run on other platforms (see to Porting the Voice Environment and Applications for further information). Portal Server 7.1 software and voice applications should use the same VoiceXML browser.
Mobile Access software supports VoiceXML applications only. If you have a legacy voice application that was not built using VoiceXML, you must provide a VoiceXML wrapper for that legacy voice application. This wrapper will integrate with Portal Server 7.1 software and manage the voice session with the non-VoiceXML application.
If you are not familiar with building voice applications using VoiceXML, consult a book on VoiceXML programming. The W3C VoiceXML 2.0 specification is the definitive reference on the programmatic elements of the language.
Mail Provider channel must be configured for voice-based access using Nuance Voice Platform and compatible phones. If Mail Provider channel is not configured, voice access to voice mails will not be available even if the user configures other mail channels like JSP comms channels.
