Comments: Like trixbox CE, Elastix is based on CentOS, and sports the same menu-driven installer, which is virtually automatic and offers very little option for customization (LVM disk partitioning is not supported).
After installation, you have the option to boot into either a CentOS Linux kernel with Xen virtualization enabled, or a kernel image without Xen. This means that you can, if there is a need for it, run multiple instances of Elastix on the same server. Elastix is one of two distros with support for virtualization enabled out-of-the-box (the other one is Vyatta).
The admin interface of this IP/PBX distro has support for 21 different languages, compared to 7 for trixbox. The admin interface is powered by FreePBX, and therefore all the features of FreePBX. Aside from the stock FreePBX features, Elastix has configuration backup and restore capability,support for video phones, Openfire (a real time collaboration server), vTigerCRM, and SugarCRM integrated, and the ability to send any digital document to a fax number through a virtual printer.
