We are a Skype for Business online customer trying to wrestle with migrating to Teams. We currently use Polycom VVX devices with the BToE tool which really works well. It is pretty clear that MS is not going to implement this in Teams, which is unfortunate and typical of MS these days - high pressure to move to the latest system even though significant features are missing or immature.
Right now we are piloting some of our IT users in Teams only mode, and BToE actually still is working, presumably because Skype is still active underneath Teams for some functions.
Our firm is not ready to give up physical phones. I realize that trying to continue using BToE with Teams is unlikely to be a supported scenario, however we are in this transition period where we're starting to migrate and interoperability between Teams and Skype isn't great, so we need to move fairly quickly; sooner than when we will be able to get Teams-native phones and/or headsets (I'm not sure if Teams-native devices will even help), so we need a stopgap solution, if for nothing else than making the migration pain less just getting over to Teams even if that means having to take away BToE functionality later.
Two questions: - What is the mechanism that makes BToE still function in Teams Only mode, and how long will this continue to keep working? In other words, when will MS kill this function - when the last Skype user in our tenant gets upgraded, a certain calendar date, etc.?
- Is MS planning some kind of BToe replacement functionality, such as answering the call on your Teams phone hardware but being able to see the call in progress on a PC or mobile device and being able to join a call in progress to facilitate switching devices or changing modes from voice only to screen sharing or video?
