[Freeswitch-users] Outbound Caller ID in a multi-Department environment

I am having an issue setting up CID for individual extensions I am running out of a PostgreSQL DB and have created a Users Table Using Lua I am dynamically generating the Directory I have a column in the table for CID, but have been unsuccessful in implementing CID for outbound calling I want the extension to display internally, but to add CID when calling outside of the system How can I implement this? And can it be done using Lua to dynamically lookup in the DB for each users CID?
