CCNQ4

SIP SoftSwitch. All core development is completed (including Voicemail), development is now focusing on extended applications (IP Centrex).

Infrastructure

• docker.freeswitch, docker.couchdb, etc. -- CCNQ4 relies on docker.io instead of Debian packages which were the norm for CCNQ3.
• ccnq4-opensips, OpenSIPS-as-Docker-image integrated with configuration, CouchDB interfaces, REST management, ... (includes royal-thing, a tool to automatically restart an OpenSIPS registrant server on changes).
• willing-toothbrush, the CouchDB-backed DNS server.
• spicy-action is a web and Socket.IO proxy to allow browser-side clients, back-ends, and CouchDB, to exchange data.
• nifty-ground, the distributed sniffer, integrated with spicy-action, delivered as a Docker.IO container.
• ethereal-banana and absurd-clover, browser-side tools to handle sniffer traces and CDR statistics.
• proud-thumb, demonstration browser tool showing call progress in real-time.
• nimble-direction, distributed CouchDB toolbox -- used to ensure individual call-processing servers continue working even in case of failure or unreachability of the master-master, main provisioning database.
• cuddly, an operations-driven, simple to use and deploy, Socket.IO-based notification framework.

FreeSwitch XML Configuration

• acoustic-line, the CoffeeScript templating system to generate FreeSwitch XML configurations.
• bumpy-lawyer FreeSwitch phrases for pronunciation of numbers, spelling words, etc.

FreeSwitch interaction with Node.js

• esl, the Node.js Promise-based interface to FreeSwitch's event socket (inbound and outbound).

Call Processing using Middleware

CCNQ4 uses the concept of middleware (similar to the ones used by Connect, ExpressJS, ...) to simplify writing dynamic call-handling applications.

• useful-wind, a middleware-based framework to build applications for FreeSwitch.
• thinkable-ducks, a npm package and Docker.IO image extending useful-wind with a REST interface and Socket.IO event notifications (to the spicy-action proxy) and embeds FreeSwitch.

Available middlewares / applications:

• tough-rate, LCR engine; provided as a Docker image with FreeSwitch, a REST interface and Socket.IO notifications. Also available is its munin plugin.
• huge-play, the base SBC middleware for CCNQ4.
• well-groomed-feast, the CouchDB-backed voicemail.
• brown-pencil the French "RIO fixe" interactive voice service (under development).
