Allowing users to Call out From Call Queues

Hello All,

We are implementing call queues within Teams Voice and want to allow users to call out using the Call queues Number. Currently the call queue has a Microsoft Teams Phone Resource Account License. We have spare Teams Phone with Calling Plan (Country zone1 - US) licenses but when I try to combine them it states that these two licenses are incompatible. We do not want to add an Operator Connect or set up Direct Routing and just want to do it within Microsoft licenses/portals. 

My Question is what license is able to be added to a Resource account license to allow for the queue to make these outbound calls. I have seen the domestic calling plan license might work but did not see anything that indicated it was guaranteed. 

Any advice/ideas would be greatly appreciated. Thank you!
