Is calling a Call Queue from an ACS app supported?

Question

Our ACS app can start a videocall a Teams user, but when starting the same call to a Teams Call Queue we get a SIP 480 disconnect. (Calling the Call Queue from within Teams works fine)

According to the Dec24 Feature Updates this feature should be GA. Any idea why this does not work?

Hi @Geert Van Houdt (HelloDoor) ,
I'm glad that you were able to resolve your issue and thank you for posting your solution so that others experiencing the same thing can easily reference this!

We found the solution. Our app used the "8:orgid" for the prefix of the ID called. But that is for calling a Teams User, for a Public cloud Call Queue it needs to be 28:orgid:<id>

Note: in the "Quickstart" link mentioned above, this prefix information is mentioned when you select Android, IOS or Windows as the platform, but not when you select Web (under "Find Object ID for Call Queue"). I think that's how we missed it.

So yes, calling a Call Queue from an ACS app is supported. Nice!

You just need to select a different prefix when calling a Teams App (like a Call Queue).
