I have a DK424 c/d v4.3 with a Stratagy DK. One of the employees, Ext. 203, was in the office now calls in to retrieve voice mail. The extention is published and can't be changed. Is there any way to keep this Ext. number but remove the phone set without getting a extention vacant when 203 is dialed. Have been getting around by having an extra DKT2010 sitting on another desk.
