Zappa is a Node.js / Express.js web server and framework based on the ideas of Sinatra.

One of the many uses I have had for Zappa includes mixing dynamic content and reverse proxying other Zappa processes and CouchDB....

Today I started a whiteboard app using Zappa. It’s usable but mostly a

The problem

The examples for Follow-Me on FreeSwitch had always left me wanted; two issues specifically were pretty frustrating:

1. Most examples use the common method of doing a bridge command with failover (using the call_timeout channel variable), for example:

We signed up for Verisign CNAM, so I'm starting to work on the CNAM Query piece of the equation (the CNAM Storage side is relatively straightforward). Specifically the fun Verisign specs (apparently claimed by Verizon under patent application 20080240383).
