Hi gang, Progress report: I removed the -b switch from my sfspeaker command and am now able to operate speak_freely directly between two users. The initiating caller must know the IP address of the person being called, but the responder can simply run the executable file created by his sfspeaker program, which contains the correct address of the caller. So - the "busy" option does not work as advertised - at least not for me. Chuck My web site is http://www.mhonline.net/~chuckh The Moon is Waning Gibbous (97% of Full)
