gaim-sip-plugin/ssip-gst: SSIP-GST is a VoIP/SIP/SIMPLE plugin for Gaim. SSIP-GST makes it possible to use Sofia-SIP library as a part of a fancy application. This is also a good example of how to integrate use of Sofia-SIP to glib based applications. SSIP-GST uses gstreamer as its media subsystem.
sofsip-cli: Sofsip-cli ( releases, darcs ) is a console mode VoIP/IM SIP client, which uses gstreamer as its media subsystem. Like ssc-gst, also sofsip-cli utilizes glib.
