I have a Call Queue setup so when someone dials Reception, it also rings on 2 other phones in case she is in one of those spaces instead of sitting at the front desk.  That works great when somebody dials the 10 digit number from outside the company. But if someone dials her 4 digit extention from withing the company, it only rings at the reception desk.  I also setup a Shared Line Group with the three phones and it still only works for the 10 digit number.  

Shouldn't the internal extention work as well as the 10 digit number?
