Forward to zoom Call Queue

Strange issue I am having. 1) Create a call queue in Zoom and assinged a DID to the queue. 2) Forwarded a number to the call queue DID. 3) Have muliple people logged into queue. 4) When the dial the fowarded number from another carrier I can head the default music of the queue and then it goes to voicemail even if there are people logged into queue. 5) If I dial the zoom DID number of the queue it works fine and it rings people phone in the queue. 6) I have tried different carriers phone forwarding with same results. Seems like zoom doesn't like a forwarded DID line to a queue. Any suggestions?
