I forward 2 numbers (work cell & work landline) to my Treo 650. Depending on where the phone calls come from (cell then its the 10 digits, or work which could be 10 digits or internal 5 digit extensions), I can't get the internal contact database to identify who the caller is (I really want the 5 digit extension to identify who it is). I have the 5 digit extensions listed in the "business 2" field in Outlook 2003. This DID work with my Samsung i500 phone.

Any ideas on which application will do what I want?
