Hello @HWHINV ,

 

Welcome to the HP community.

 

Unfortunately, your post does not contain the currently used Software version for the HP Poly product or the exact Partner application version you use.

 

For example Microsoft Teams, Zoom Rooms, Poly SIP/H.323 mode 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.

 

If no other volunteers reply, I suggest you contact our Support organization in your region. Details are in my Signature.

 

Best regards

 

Steffen Baier
