Hi Freddy,
I wrote a Python/Flask web dashboard for mod_callcenter two years ago. It is using mod_xml_rpc to access FreeSWITCH.
This was adapted from an Asterisk Queue dashboard I wrote before, hence the slightly modularized backend. It was only used internally up to now.
As this might be useful for you or other people, I just got permission to push this to Github, so here it is:
I just added a quick README.md, the code itself is running unchanged since 2012 in an environment of < 50 users/agents and a few queues. Strings are Geman only, but that can be easily changed.
Best regards,
Markus
