We have rolled out the ZIA App to our organization - but we have felt some issues with the o365 One Click - The main bug being intermittent silent calls when using MS Teams Enterprise Voice. As a test, we assigned some test users their own app profile, and bypassed everything Microsoft related from https://docs.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide
This has had a positive affect and vastly reduced the silent calls.
Mgmt have decided they want to roll out o365 bypassing to everyone - is there a clean or recommended way to achieve this? An api maybe?
