Hello pokotony,

welcome to the Polycom Community.

It is always useful to include the currently used software version as issues experienced may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes in order to verify if the combination of Polycom and other third party manufacturers have been tested and the software version classed as supported.

The HDX 3.1.5 release notes => here <= state on Page 72 the products tested against this release.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Steffen Baier
