Call queues and auto attendant issue.

Hi All.

I have set up a clients tenant with a resource account and virtual phone system license to allow me to set up a call queue. I have set up the queue added agents etc and assigned it a phone number via powershell.  However when I call the number assigned the SBC tells me the user doesnt exist.  This client is setup to use S4B as their endpoint in coexistence mode.  Will this have an impact to using AA/CQ via direct routing?
