Hi,
 I've noticed that we get many CDR records with failure code 'Facility Rejected' when calls made from voice mail ports to our on/off MWI numbers.  Upon further inspection, it seems these calls are made to unassigned DN's which still have voice mail forwarding settings. 
 
It 'seems' like what's happening is UC gets the call but doesn't realize there's no phone attached to the DN to turn on/off the light and tries to make the call anyway resulting in these false failures. 
 
Is this a known bug? If so, when can we expect it to be fixed? If not, can someone please file it?
 
Thanks
