Hello @stephan greve ,
Welcome to the Poly Community.
The BToE 4.4.0 release notes >here< are pretty clear on this:
The Polycom BToE Connector application 4.4.0 is compatible with UCS 5.8.0 and later.
If you plan to upgrade to UCS 5.9.6 or UCS 6.3.0 and want to use the BToE Connector application 4.4.0, you must upgrade your software in a specific order:
- If you are running the BToE Connector application 3.8.0 or later with UCS 5.8.x or 5.9.x, first
upgrade your BToE application to version 4.4.0.
- Next, upgrade UCS 5.8.x or 5.9.x to UCS 5.9.6 or UCS 6.3.0 to retain successful pairing.
If you have older software versions (BToE Connector or UC software), read EA 318 and refer to the Polycom UC Software 5.9.6 Release Notes or Poly UC Software 6.3.0 Release Notes before you upgrade your software
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
