Need to support external clients for all existing features of Skype for Business
If Teams is to replace Skype for Business it has to support external users. We use this feature extensively. We need to collaborate with partners which are OUTSIDE our company domain. We need an easy way to add "teams" that adds outside users (in our case from partners) and provide all the features that Skype Business did like phone calls, IM, Conferencing etc. I could not find an easy way (or at all) to do this. If that isn't provided we would have to skip Teams (old Skype) all together and get another vendor to solve this business need.
We NEED external users to be able to call in and have it work without issue - this Teams video chat does not function like Skype or Skype for Business, where Anyone is reachable and can have a large group join - Teams does not allow this, and we have to resort to using telephone without Webcam view, or GoTo Meeting - Webex does not even work the same
