Hello, o Steven C. Blair [05/20/08 20:13]: yes, you can use it now with any SIP proxy thanks to its own SIP stack. I'd recommend you the pretty fresh SEMS 1.0 RC1 which is available for download at http://ftp.iptel.org/pub/sems/sems-1.0.0-rc1.tar.gz (debian package here: http://ftp.iptel.org/pub/sems/testing/sems_1.0.0-rc1_i386.deb ). For a mere conference bridge, load conference application, sipctrl application (sip stack), and codec modules to taste (wav, speex, ilbc, gsm, adpcm, l16). Needed modification to the default config file would be the following in sems.conf: load_plugins=conference;sipctrl;wav;ilbc;gsm;adpcm;l16;speex application=conference listen=... sip_port=... hth Stefan Sayer -- Stefan Sayer VoIP Services stefan.sayer(a)iptego.com www.iptego.com iptego GmbH Am Borsigturm 40 13507 Berlin Germany Amtsgericht Charlottenburg, HRB 101010 Geschaeftsfuehrer: Alexander Hoffmann
