We have found if you enable EC500 (CM6.0), call hits your office extension and rings both that & your cell...if you deny the call on your cell, it goes to your cell voicemail and not back to your office voicemail. The only way it will go to your office voicemail is if you don't touch anything. Seen this? Just the way it works? Or, a way to get around that? We do not want users to have business calls going into their cell voicemail.
