I was testing new normalizing rules in Company_Phone_Number_Normalization_Rules.txt but to be sure when the Communicator get's the right GalContact.db, I found this information.
You don't need to see GalContact.db in notepad, you can export it to CSV :)
Create the following reg key:
sign out and back in again
You can find the Contacts.csv file directly from MOC, select Tools -> View Received Files.
Remeber to set DumpContactsToCsvFile back to 0 or delete it.
