I have seen following note on Microsoft’s docs.
“The Skype for Business Bot Framework channel is in Developer Preview and is not licensed for production usage. This channel will not be supported after 6/30/2019. As part of Microsoft’s intelligent communications vision, we’re building extensible communications capabilities into Teams.”
I could see all the steps to enable channel in your documentation.
Does Skype for business as a channel in Kore.ai still available? If available will it work properly? I have tried in Microsoft azure account after bot channel registration there was no Skype for business channel was available.
