Do "intrastate" versus "interstate" billing rates make any sense whatsoever in the world of SIP where geography ceases to be relevant? There is a fundamental disconnect today between the legacy world of PSTN billing practices and this new world of SIP-based interconnection that we are all building. The Internet ignores geography. We can connect to any random points in the cloud, regardless of where they are physically located. But until the day when we have truly built the IP-interconnect and can all be bypassing the PSTN, we do have to deal with the PSTN..... (Read More)

What is a "State Machine"? And how does it apply to CCXML (and James Bond)?

When people come to CCXML from other languages, one concept that is sometimes difficult to understand is the whole notion of a "state machine". Once you are comfortable with that idea, CCXML becomes rather easy to work with. While the Wikipedia page on state machines gets quite complex, let's reduce the concept to some basics. First, some vocabulary. In a "state machine", there are a series of "states", such as being "on" or "off". There are then "events" that cause there to be a "transition" between states. Now to illustrate.. (Read More)

Posted to Voxeo TalksMay 9th, 2008 by Dan York
Have you checked out the Party Line application for Facebook that I wrote about a few weeks back? Well, the folks at Equals have spent some time working on the application and listening to the feedback from users. They've made some changes to it and also clarified some of the usage terms. Here are the major changes: Removed the initial advertisement that people being called out had to listen to when they were put into a call. Callers now just get dropped immediately into the conference bridge so that you can start.. (Read More)
Accessing Web Services From VoiceXML
Posted to Voxeo Developer's CornerMay 8th, 2008 by Mark Headd
This is a guest post from Mark Headd, a voice application developer who was one of the first 10,000 users of our platform, and was originally published on his Vox Populi blog on May 6, 2008. A few weeks ago, I posted about accessing web services from CCXML using PHP. This post will demonstrate how to do the same thing, only from VoiceXML. We’ll be using Voxeo Prophecy and PHP for this example. We’ll also be referring to the GreenPhone project — available free for download — for the sample code. Before we.. (Read More)
