</span><ins>+morse.js - lets you send audible morse code to a conference or uuid
+ cp to /usr/local/freeswitch/scripts (or wherever it was installed)
+ see script for usage information.
+fs_rpt.pl - lets you bridge your ham radio (or other) into freeswitch.
+ requires morse.js for CWID identification if you are using it
+ like a repeater and your jurisdiction requires this.
+ requires a hardware adapter to key the mic.
