Modules providing predictive dialing can be added. It is a fork of the open-source versions of Elastix, developed by the user/developer community when 3CX acquired Elastix, closed the community, halted distribution and development of the open-source versions, and released a proprietary version.<ref>{{cite web|last1=Landivar|first1=Edgar|title=Perspective on Elastix - 3cx Changes|url=https://www.elastix.org/blog/latestnews/perspective-on-elastix-3cx-changes/|website=www.elastix.org|accessdate=7 January 2017}}{{Dead link|date=August 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><ref>{{cite web|last1=Igarto|title=De la muerte de Elastix, al nacimiento de Issabel|url=http://blog.desdelinux.net/la-muerte-elastix-al-nacimiento-issabel/|website=DesdeLinux|date=14 December 2016 |accessdate=10 January 2017}}</ref><ref>{{cite web|last1=Cabrera|first1=Christian|title=Issabel: una alternativa de código abierto|url=https://asteriskmx.org/issabel-una-alternativa-de-codigo-abierto/|website=Asterisk Mexico|date=14 December 2016 |accessdate=10 January 2017}}</ref><ref>{{cite web|last1=Rojano|first1=Elio|title=La comunidad Elastix crea el proyecto ISSABEL|url=https://blog.sinologic.net/2016-12/la-comunidad-elastix-crea-el-proyecto-issabel.html|website=SinoLogic|accessdate=10 January 2017}}</ref>
