Welcome to the HP community.

Unfortunately, your post does not contain the currently used Software version for the HP Poly product. Also who is you provider? For example, Microsoft Teams, Zoom Rooms, openSIP/H.323 etc.

This is important, especially in the future, when someone finds this post in days, months, or years.

Please do not simply edit the original post but reply with the versions.

In the FAQ or the Read 1st section, we remind users why this is important.
