VXML
Voice Extensible Markup Language (VXML) is a World Wide Web Consortium (W3C) standard that allows voice-based interaction
between human users and computer applications. VXML is used for applications and systems such as auto-attendant, voicemail, or
IVR, with VXML scripts performing functions such as playing prompts, collecting user input (speech or DTMF tones), and routing
calls.
VXML scripts can perform IVR functions similar to Tool Command Language (Tcl) scripts; the major difference is that whereas Tcl
scripts are usually device memory resident or downloadable from a TFTP server, VXML scripts are usually interpreted by a voice
browser after they are downloaded from a web server using HTTP. (VXML operates using a client/server model.)
UCCX supports VXML 2.0 applications.
