SFLphone Open Source SIP


SFLPhone Default Skin

An interesting new SIP softphone client to bring to light called SFLphone that I don't think many people know about. It's similar to the popular XTen SIP softphone client in that both are SIP-based, however unlike the Xten softphone client, this SIP-based softphone is "open source". So if you are a developer you can start hacking away at the code to tweak it your liking. It also supports "skins" so you can customize the "look and feel" of the graphical user interface.

Now I don't want to get into comparisons between the two, that's not the point of this blog entry. I love the Xten softphone, but it's always nice to see open source solutions.

Also, the SFLphone is in "alpha" but it is already able to register to SIP proxies, place calls, manage lines, put calls on hold and transfer them, and use STUN.

It had the following features so far:
SIP and STUN support ;
OSS audio devices support ;
Skinned GUI ;
G711u and G711a PCM codecs ;

Additional features are planned, including but not restricted to :
Desktop integration, dial from your browser/addressbook/... ;
LDAP enterprise directory support ;
The IAX protocol, for more inter-operability with Asterisk servers ;
ALSA (90% done), MacOSX and Win32 audio support ;
Non-QT and/or pure-QT GUIs for different systems, if needed ;
Support for more codecs (GSM ready to merge, Speex, iLBC, ...) ;
Native support for video ;
Autoconfig from remote server ;
Secure transmission channels ;
Plug-in support so you can script your phone to interact with incoming or outgoing calls ;
