For the past 4 months I've been working with two other colleagues (in Cc) on an OpenSource project to monitor the FreeSWITCH Softswitch in real-time via ESL events.

Our background is in Telecoms so that is where we're coming from with the dashboard: You can see live call numbers, and you can click and drill down to see call details. We also provide KPIs like ASR, ACD, Dialcodes matching etc. - functionalities that will help anyone using FreeSWITCH as a SBC or using FreeSWITCH to pass traffic that's originated from a sip proxy like Kamailio or OpenSips, and also to help users understand what is happening in their FreeSWITCH instances in real-time. 

Here's the git account, and the live instance of the dashboard is here. The credentials are admin/admin

I hope you will find it useful and we are awaiting for your feedback!

Thanks for taking the time to read this rather long email!

Kind Regards

Alex
