After you configured and started the Capture Agent inside FreeSWITCH, make a call.

Then, log into your Homer, set the Time Range to Today, select calls as transaction kind, and click search.

You'll be greeted by a tabular view of the SIP signaling comprised in your call. If you get no results, check the homer_data database if sip_capture_call_2016* table has been created for today. If not, execute as root /opt/homer_rotate.

If you click on the Method name, a popup springs up showing the whole message, with nice coloring.

If you click on the CallID field, you can peruse the entire end-to-end Call-Flow, in sngrep/wireshark style.

Clicking on a method inside the Call-Flow popup shows a new popup with that whole message.
