Fedration enabled on premise skype for business with bot framework : I have a bot that is successfully running on localhost and also with ngrok and webchat.
I know that Skype for business channel can only be enabled for Skype for business online and office 365 online.
Now I want to now, can federation enabled on premise Skype for business be integrated with Microsoft bot.

Note: Federation enabled on premise Skype for business is on a virtual setup and behind a company firewall.

I am confused as I can be found by the employees of other companies who also use Skype for Business then should not on premise Skype be able to connect to Microsoft Bot Connector.
