Teams Resource Account - Setting Call Priority

Being able to set a call priority within Teams is relative new

https://learn.microsoft.com/en-us/microsoftteams/aa-cq-call-priorities

The easiest way that looks to be enabled is when using a resource account, and assigning the association to either a Teams AA or CQ.

New-CsOnlineApplicationInstanceAssociation <ID of the resource account> -ConfigurationId <ID of the AA/CQ> -CallPriority <call priority number> -ConfigurationType <autoattendant|callqueue>

Call Priority Values are:

1 - Very High

2 - High

3 - Normal (default priority)

4 - Low

5 - Very Low

This will throw an error if the RA is already associated with a AA/CQ, to remove the association we can use the 

Remove-CsOnlineApplicationInstanceAssociation <ID of the resource account>

To view the call priority value of the resource account

Get-CsOnlineApplicationInstanceAssociation  <ID of the resource account>

Teams Resource Accounts

Trying to crate a "Resource Account" for a Teams CQ and/or AA, and came across an issue where via both TAC and Power Shell it would fail.

TAC

Power Shell

I had seen this before when the Teams/Skype Online was a Hybrid environment, but in this case the deployment has no on-premises Skype environment.

The Fix

Turns out DNS is the issue, even when in a cloud only environment the Skype DNS entries are required.
