PhoneGaim
From Wikipedia, the free encyclopedia
PhoneGaim is a free software VoIP system based on the Pidgin instant messaging software and the SIP protocol handling of the Linphone VoIP software, but restricted to using (only) the SIPphone service. It is available under the GNU General Public License and sponsored by Linspire.
Some controversy exists over the perceived difficulty faced by non-Linspire users who wish to install PhoneGaim on their Linux system.
Linspire has released another multiplatform proprietary SIP client called Gizmo Project to compete more directly with Skype.
