As the title expresses, several users in my organization aren't receiving calls specifically on the mobile app - with zero changes to the system. It was working flawlessly earlier today. The desktop app still functions properly and the desk phones still work for those who use them. Anyone else have this issue? Any suggestions? Currently on hold with chat support (I've been waiting 30 minutes already..), and can't call in because the phone system tells me that my PIN for my voicemail is incorrect - when I know for a fact that it is not.
