Populate Business 2 phone number from active directory

All,

I was trying to populate Business 2 phone number in the address book from the active directory, I have read that if I added additional phone number in the general page it will do the work but it didn't work for me.

either this or if some one can help me changing the "Home" number display name like instead of showing it as "Home" I want it to be "Direct Line

Thanks"
