Transfers from Auto Attendant to Dynamic Extension won't go to VM

[JohnGoodie]

Transfers from the Auto Attendant to a dynamic extension will ring and ring and not go to voicemail.  It works fine if I turn off the dynamic extension.  The dynamic extension is set to go to VM on Step 2.  Any help is greatly appreciated!  Thank you! EDIT: By the way this is a Mitel 5000 system.
