VBSS causes audio shift

[JamesW]

Skype for Business Server 2015 (on-prem)

Skype for Business 2016

Lync 2013

UC Firmware 5.8.1.6389

On a Multi-party Skype conference call where VBSS is used / enabled, when a presenter on the call starts screen sharing with VBSS the audio is shifted from the VVX to the Skype Client.

Is this expected with VBSS sharing?

I also see this behaviour when someone in the call starts video, I expect this behaviour in this instance.

Hello @JamesW,

welcome back to the Polycom Community.

I am scared to ask tonight as people seem sensitive but are you using BToE by any chance?

Yes. BToE 3.8 and UC Firmware 5.8.1

Hello @JamesW,

from the 5.8.1 release Notes:

• When BToE is enabled and the video-enabled phone is paired to the Skype for Business
  client on your computer, the preference for transmitting and receiving video streams is
  given to Skype for Business client. The preference is given to VVX phones only when the
  phone unpairs with the Skype for Business client. You can place all Skype for Business
  related calls from VVX phones as audio-only irrespective of the call mode selected on the
  phone. However, users can choose to enable video from the paired Skype for Business
  client.

I understand and expect this behavior with video. In this instance it isn't video, but desktop sharing that's using the VBSS protocol rather than RDP. I find the behavior surprising in this instance and don't see it addressed in the documentation. James

Hello @JamesW,

VBSS is Video Based Screen Sharing aka a Video Session unlike the "old" RDP which is a remote desktop protocol.

This is WAD and any change would require a feature request.

If  you still believe this should be dealt with as a Bug please open a ticket.

In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.

End Customers are unable to open a ticket directly with Polycom support.

If this is some sort of an Internet discounter providing your MAC address or your Polycom devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Polycom device from.
