   Hi Erik, thanks for the nice summary. Something to keep in mind: when you use Users, Groups or both instead of a Team/Channel to add the agents to the queue, the additional Calling Line ID will still show up in the Calls App / DialPad. However, in my tests, using it for outbound calls did not work unless you configure a Team/Channel as Agent List.

   Also, that’s the second time I read somewhere that using collaborative calling would only deliver calls to the Teams Desktop Apps. Where did you get this info from? It doesn’t matter which method you chose, Team/Channel, Users, Group or Group and Users, in the end, Teams will expand the Team and all Enterprise Voice Enabled users to the CQ “internal” AgentList. Agents will still receive calls on Mobile, Web, Desk Phones even when Voice Enabled Channels are used. Users can still Opt-In/Out from CC Queues through Settings when using the Mobile, Web or Desk Phone Apps. Only the Calls Tab inside the Channel is not visible on devices other than Desktop. On Mobile, additional Calling Line IDs have been available through the Calls App before it was rolled out on Desktop.

      Hi Martin,
      Thank you for your comment.

      That’s an interesting point in my tests above agents where direct CQ members (added as users). I could change it to a collab calling channel and back, just to see if it makes any difference that the CQ object gets updated.

      Regarding the collab calling there is a compat. list by Microsoft docs (link below) showing that it is only supported/working Windows, Mac and VDI clients. I tested this in an early stage in March 2021. Maybe this is no longer up-to-date?

      See https://docs.microsoft.com/en-us/microsoftteams/create-a-phone-system-call-queue?tabs=general-info#call-queue-feature-compatibility

         Hi Erik,

         I noticed the first point because I wanted to set it up for a customer and I couldn’t get it to work without using CC assignments.

         Ah I see, I also saw that compat list. I think they just mean that the Calls Tab within the channel is not supported on Mobile, Web, Ip Phones etc. We use a CC Queue in Production and I’m 100% sure that calls from a CC queue can be received on mobile because I answer a lot of them on mobile.

         I just wanted to ask why you thought that calls from CC queues only hit desktop users but now it’s clear.

            Hi Martin,
            Thank you for your feedback.

            I made some further tests in my lab. 😀
            Making outbound calls worked in both scenarios, i.e. (test 1) agents added directly in a CQ and (test 2) agents being part of a Teams channel. What I did not test is if there is a difference adding users in group to a CQ.

            Moreover, I tried calling a CC with Teams mobile app users-only. It worked (on iOS). I’m excited about this. 🙂 However, I will still be cautious because I’m not sure if this is or could be subject to change? I might just open a request via Git to update the documentation.

               I want to use this option too, but I noticed that if I have an autoattendant using an AA-resource with number +3120xxxxxxx (the number of our servicedesk) and I want to assign that same resource to the queue with agents so they can use that number to dial out, it won’t let me because ‘resource is already in use’. Also cannot make a CQ-resource with that number because ‘number is already in use’. Looks like I’m stuck with the CallerIdPolicy and force the outgoing number that way…..any thoughts ?

               I came across something these days.

               I think there is/was an issue in the backend. You might re-check if this works by now. Check out these two resources:

               unfortunately, still get the error that I cannot assign the RA of the AA to the CQ.

               Has the AA‘s RA a voice routing policy assigned (direct routing)? If that’s not going to make a difference I‘d give it a try with another RA/AA/CQ to test if it occurs only with the existing one or others as well. At last you might raise a Microsoft support ticket.
