I setup Office 365, added telephone system, calling card and domestic/international calling credits. But I am unable to use Skype.
I have the telephone dial button console in my skype for business App, which shows that the calling card has been setup successfully.
But I can not make any calls, my mic also does not show as being connected. (all other apps - no problem) Also I am unable to make a call quality testing call. Which shows there is a block somewhere on the software.
Love some help
