Hi,
 Our CUCM environment has 10 digit DN's and we have translation patterns to allow for abbreviated dialing.  However, when a call is made from IP phone to IP phone dialing the 4 digit abbreviation, the CDR still shows the full 10 digits for the originalcalledpartynumber.  I would have expected it to be 4 digits and the finalcalledpartynumber to be the full 10.  
 
Has anyone else seen this behavior or is able to explain it?
Thanks
