Last few month were very busy here in Nettigo. Before December 2008 we were working mainly for customers in Western Europe and USA. Starting from Decemeber number of requests for development in Rails coming from Poland (where we are located) have raised significantly. Seems like Rails become more popular here (finally :)) )
One of those request was for web based solution to provide billings to simple VoIP installation. As result we have created CDR billing. This is simple software to analyze billing entries in CDR format from VoIP system and provide billing reports.

VoIP phones billing? No more a problem. Img (c) http://flickr.com/photos/esparta/
Currently it supports Cisco Call Manager Express (in other words - solution available for VoIP network built with Cisco’s routes, without Call Manager appliance) for logs in compact or long format. But there is no problem to add support for Call Manager Cisco appliance logs or Microsoft’s Office Comunications Server. Or other VoIP system - You name it.
Use case
CDR billing was written with following use case in mind:
- small/medium sized company using VoIP telephony system on own network infrastructure
- company want to know costs associated with VoIP usage by particular person
- people using VoIP are associated with division/branch so reports do also cover how costs are spread between divisions/branches
Technical details
System is written in Ruby on Rails and can be run on Linux (recommended) or Windows servers, uses MySQL as database. It can be customized to match additional requirements.
CDR billing does not collect logs from Cisco devices by itself, it requires logs in CDR format being available in local filesystem.
