Hello @CBTECH ,
Welcome back to the Poly Community.
As already outlined by @rgsteele >here< our Partner Microsoft owns the Microsoft Teams IP Phone app so the quickest way most likely is to check in one of their dedicated forums. Maybe give this >here< a try?
If you still want to pursue this here we would need to get more information on the call flow in place.
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.
Best Regards
Steffen Baier
