SFLphone is a SIP/IAX2 compatible softphone for Linux. The SFLphone project's goal is to create a robust enterprise-class desktop phone. While it can serve home users very well, it is designed with a hundred-calls-a-day receptionist in mind.
SFLphone is a free software and is distributed under the GNU General Public License version 3. It is developed by Savoir-Faire Linux, a Canadian Linux consulting company, in partnership with the global community. Savoir-Faire Linux provides to users easy-to-install packages for most of the main Linux distributions.
