No there is no GUI to administer Freeswitch. However, you can manage your freeswitch log with some simple commands given below:
Freeswitch command line interface: /usr/local/freeswitch/bin/fs_cli
View and manage your gateways: "sofia status" (write at cli)
Reload and update freeswitch configs: "reloadxml"
Apart from that, If you want to further manage your system, ICTFax2.0 have two other logs that admin can check.
1. Web log: admin=>Reports=>Recent log messages
2. Files log: /tmp/mytest.txt ($ cat mytest.txt )
