Ryan Steele You should consider 3PIP phones to be deprecated. Don't expect any new development. We used to be able to use the 3PIP phone as a microphone (and speaker) for the soft client (for SfBO), using Better Together over Ethernet (BToE), but Microsoft has already stated that the Teams soft client will not support BToE with 3PIP phones. They are working on a Bluetooth solution for the newer Teams native phones (Android based). Microsoft has provided backwards compatibility for the 3PIP phones to act as basic phones, which works well for stand alone common area phones and also makes it so we can get a little more life out of these phones that have been recently purchased (in the last year or so), even as user desk phones (but they will lose the BToE functionality). It isn't perfect, but at least we aren't throwing all these new(ish) phones away.
