Main Page
SARK/SAIL is a fast, lightweight, Asterisk-based PBX, with a browser GUI component, a SIP provisioning system, an Asterisk code generator and a compiled logic and switching engine. It currently runs on Debian and Ubuntu on both i386 and ARM 64 bit devices. SARK and SAIL are essentially the same product, the difference is that SARK is the supported commercial release while SAIL is supported by the community. The product has established a reputation for being easy-to-use with a very small footprint while being functionally able to compete with and exceed traditional proprietary PBX offerings at a much lower overall cost-of-ownership.
SARK is delivered as a series of .deb packages ready to be installed onto an existing Debian or Ubuntu 64 bit image.
The commercial version of the software is marketed under the SARK and MANX brandnames. The free-to-download version is called SAIL (SARK Asterisk Integration Layer). The main difference between SAIL and the commercial versions is that SARK and ManX are supported by Aelintra Telecom Limited while SAIL is supported by the community. You will see the words 'SARK' and 'SAIL' used interchangeably throughout these pages.
SARK/SAIL is distributed under the terms of the GPL and other licenses.
