Allow management of Teams voice, call queues and auto attendants etc through graph
We have a management platform that automates, among other things, onboarding and offboarding of Teams users. This includes provisioning of voice services for those users. We also automate management of auto attendants and call queues. Finally, we orchestrate migration of voice services from legacy PBXs (e.g. Cisco Call Manager) to Teams - hunt groups and auto attendants to Teams call queues and auto attendants, as well as end user migration. To accomplish all of this we currently, out of necessity, use PowerShell and service accounts with administrative access, and without MFA. We are receiving a great deal of pushback from our service provider and enterprise clients about our use of admin accounts for this, but at this point there seems to be no alternative. We would like to see one of two things: either full support for modern authentication in the Teams PowerShell module, or Graph API support for Teams voice services (formerly Skype for Business Online).
