Admin Pin this is the pin used to make recordings using the *732 feature code. Not sure if it is used for any other purpose. (As of v 3.6, the PIN for creating recordings lives in the Dialplan Manager page. Click Dialplan -> Dialplan Manager -> recordings.    In the rules, note the one which says "pin_number")

This page has settings for:
 * numbering plan - determines how phones numbers are constructed
 * area code - the default area code for 7 digit calling

It is not completely clear what the purpose of these is, however this XML snippet from directory/default/default.xml may shed some light on this. These appear to be default values and are set by FusionPBX in this file. It is possible that you can create multiple dialplans on a freeswitch/fusionpbx server that are specific to users based on overriding these default values. all variables here will be set on all inbound calls that originate from this user set these to take advantage of a dialplan localized to this user
