Microsoft Teams Mute Synchronisation with Biamp’s EX-UBT



The HID functionality offered by Microsoft in conjunction with the EX-UBT offers a next generation of functionality to provide an extraordinary user experience using soft codec conferencing standards.

Microsoft recently implemented some exciting new updates to MS Teams to provide enhanced Human Interface Device (HID) controls with products made for Teams.

One of those key products made for MS Teams is the new Biamp EX-UBT USB+Bluetooth expander device.

The Biamp EX-UBT offers a networked USB interface for PC, Macs and appliance codec devices to support the growing uptake of soft codec USB conferencing platforms and provides significant advantages over traditional USB extension interfaces.

Unlike traditional point to point USB extension over dedicated and often proprietary cabling the EX-UBT uses IEEE networking standards, and existing network infrastructure, for reliable extension over Cat5e or better up to 100m between switches.

It's compact size, and extension over standard network infrastructure, allows for a centralised DSP topology with local USB interfaces. This reflects the industry shift away from in-room credenzas full of AV hardware to a more centralised, IT centric hardware approach.

Unlike other networked based USB interfaces the EX-UBT is a fully configurable device offering AEC offloading when configured as an Echo Cancelling Speakerphone device. This means that you won't experience the unwanted artefacts or compression associated with performing simultaneous software and hardware based Acoustic Echo Cancellation (AEC).

Made for MS Teams, the EX-UBT uses these HID drivers to guarantee AEC offloading, as well as provide two-way control communication for mute status synchronisation between Tesira and the soft codec.

Using the EX-UBT we can receive the current mute status from MS Teams HID drivers in the form of mute logic. We can also send a mute status change from Tesira to MS Teams again in the form of mute logic.

When mute is initiated from the 3rd party control system a network string sets the Logic State block to high or low. This change sends a HID command to MS Teams and a logic command to the approved microphone notifying, of the mute status change.
