Hello @SteveSD ,
Welcome to the HP community.
Unfortunately, your post does not include the currently used Software version for the HP Poly product you are using.
This is particularly important, especially in the future, when someone comes across 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.
I would suggest you contact our Partner, Microsoft, as they own the platform you are trying to use.
Best regards
Steffen Baier

Yes
1. request a shared license number
2.create a zero touch common area phone signin (has to be done by a global administraor)
3.you will need to create a bulk signin CVS file
Configure SIP Gateway - Microsoft Teams | Microsoft Learn
4. need to create a common area phone policy also.
all of the steps are on the microsoft Learn site.
hope this helps
