I had a few issues getting the freeswitch agent-local to work. In the end the fix was simple. The FSCLI path was wrong in the /opt/librenms-agent/agent-local/freeswitch file. I found the correct path by running find / -name fs_cli and editing the FSCLI=/usr/bin/fs_cli to be correct.
Update: If you would like the Apache Status to work add the following to your apache config /etc/httpd/conf/httpd.conf
Deny from all
Allow from localhost 127.0.0.1
You can check by running /opt/librenms-agent/agent-local/apache
