• Defining and assigning the custom security attributes requires the Attribute Definition Administrator and Attribute Assignment Administrator roles; by default Global Administrator and other admin roles cannot read, define or assign custom security attributes. in context
• The Conditional Access policy is then edited so that Target resources includes All cloud apps and the Exclude tab uses Edit filter with the custom attribute, operator Contains, and the value assigned to the SIP Gateway apps. in context
• The SIP Gateway resources cannot be excluded from Conditional Access policies directly, and excluding the apps alone is insufficient because they depend on the Teams app for scopes; Microsoft instead documents a dynamic app filter based on a custom security attribute. in context
• The dynamic filter procedure requires service principals in the tenant for SIP Gateway API (0ab9de21-b802-4d77-b279-1ad41ca233b4) and SIP Gateway UserApp (582b2e88-6cca-4418-83d2-2451801e1d26), plus Teams SIP Gateway (61c8fd69-c13e-4ee6-aaa6-24ff71c09bca) when bulk sign-in is used, each assigned the custom security attribute. in context
