Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Cirpack develops local exchange and transit switches for telecom operators to deliver all the primary line voice services over legacy TDM networks as well as new broadband local loops using VoIP protocols. Cirpack switches started to be developed in 1997 as an R&D project within alternative operator Kaptech. At this time, market deregulation stimulated the founding of many telecom operators looking for TDM Class-4 and Class-5 switch alternatives. Cirpack was the first voice switch on the market to use off-the-shelves hardware and open-source software to replicate the features of old proprietary switches at a fraction of the costs.
