The CallXML platform is available exclusively from Voxeo. As a simple markup language with a short learning curve, it suits the needs of most telephony applications that use touchtone input, DTMF. CallXML allows for faster development of IVR applications from conceptualization to deployment due to it’s easy-to-learn syntax, as it does not require complex SRGS voice grammars in order to operate.
