Equally important, services must also deliver convenient access with ever-faster performance. Rather, it supports accompanying standards, such as HTTP, SSL, and cookies that make it possible to deliver secure solutions for mission-critical applications. Moreover, because VoiceXML is built upon existing Internet standards, companies can literally reuse their existing Web-based framework for security, authentication, and personalization when extending services to the phone.
