Remember when VoiceXML was the next big thing? The good news is that it did create a standard programming interface for telephony engineers to develop voice applications once and deploy them on the telco infrastructure of their choice. It’s still heavily utilized today. In fact, most of the enterprise IVR applications are delivered as VXML applications.
One of the problems with VoiceXML is that all of the telco’s implement the VXML spec slightly differently and you need to “fiddle” with your voice application until it works with a new carrier. While this doesn’t promote vendor lock-in, it helps. VoiceXML is a very powerful interface which will meet almost any voice engineer’s requirements; however, it’s complex and typically requires classes and even certification to accomplish. This is certainly not the case for PhoneML, our phone web service language.
Teleku recognizes the power of VoiceXML and designed our platform to leverage it. In fact, VoiceXML is at the heart of our delivery vehicle for interfacing with telcos. Any telco vendor that supports VoiceXML (99% of them) can now accept Teleku originating phone calls running PhoneML and TwiML (and even VoiceXML) applications. We believe that this design will allow us to scale across all telco platforms leveraging unused bandwidth and reduced voice/SMS rates.
We have partnered with Voxeo first because we believe that they are the most technically advanced telco provider in the market. Other telco carriers looking to get into the cloud communications space should contact us and find out how easy it is to get started. Email info [at] getvocal.com.
