Support for portable wifi enabled phones or Dect
Allow vendors to develop and deploy wireless portable devices for calling.
There is no device on market for both Skype online or Teams that is Wireless and portable. Deploying mobile phones with Teams or the Skype at is not professional and does not work well in testing.
Vendors have claimed this is due to Microsoft refusing to certify this type of device.
Something like the Spectralink 8440 is the kind of device that I think we're talking about here. We currently use them for our shop personnel and the service is from RingCentral.
The 8440 also comes in a Skype-for-Business flavor, which is interesting, since that product is being depreciated and replaced by Teams. Hopefully, they come out with hardware that allows users to authenticate to teams and have direct-dial numbers there.
