Wazo is a PABX application based on several free existing components including Asterisk and our own developments. Wazo provides a solution for enterprises who wish to replace or add telephone services (PABX).
Wazo is free software. Most of its distinctive components, and Wazo as a whole, are distributed under the GPLv3 license.
Wazo is a fork of XiVO, which was created in 2005 in France by Sylvain Boily and the company Proformatique. In 2010, Proformatique merged with Avencall, and Avencall acquired the copyright and trademark of XiVO.
Sylvain then moved to Quebec City and founded Proformatique, Inc. where the XiVO core development team worked from 2011 until November 2016.
In November 2016, Proformatique Inc. was shut down and the development team forked XiVO to create Wazo. Its first release, Wazo 16.16, was released in December 2016.
