Unison Technologies' Linux-based unified communications software is now available for instant testing.
The Unison Server unified comms system was launched at this month's CeBIT show, and the firm has now released a live demo version.
The demo allows users to test out features such as click-to-call and integrated e-mail and instant messaging without having to install their own copy of Unison Server.
The full system combines telephony, e-mail, instant messaging and collaboration into a unified product, with a Linux server and a Windows desktop for users.
"The Unison demo will allow thousands more people to try our product in the coming weeks," said Igor Balk, Unison Technologies' CTO.
"By simply downloading the Unison Desktop client and connecting to our managed demo servers, they can immediately experience some of the benefits of fully-unified communications."
Unison Server is in beta until the third quarter of 2008, and Unison promises small and medium-sized enterprises a "far superior alternative to costly and non-unified telephone and e-mail systems".
