Internal (Company) Directory Setup (v2.7)

Where do I fill in the internal directory information for callers to be able to use the dial by name lookup feature?

I am running FreePBX v2.7 installed as part of Elastix v1.6 running on Asterisk v1.4.26.1.

I just can’t seem to find anywhere on the GUI. I can only find the asterisk phonebook which I assume is to consult for calling out, but I need the one for the company internal directory.

I know it must be obvious for anyone with experience, but this is my first installation attempt.

Much thanks,
