Trio C60 Microsoft Teams and Firewalls

I am attempting the sign in of a Trio C60 to Teams and for the most part this appears to be successful as it appears in the Teams portal as signed in.

We run a pretty tight firewall so with some further investigation I have discovered that our firewall is blocking a lot of requests off to a few different IP addresses. see below;



My question is this, is there a definitive list of Microsoft subnets that I will need to give these devices access to?
