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.
Based on a client/server architecture (communication through DBUS), it provides a GNOME client, a KDE client and a command-line Python client, all clients using the same SIP core.
This project is licensed under the terms of the GNU General Public License 3(GPL3). SFLphone is currently in active development, developers & contributors are welcome.
