[Zope] Customer Relation Management

Hi All, I am new to Zope. Have been searching the website(s) and archives but can't find what I am looking for, so here is the question. Does anyone know off an application for Customer Relation Management with Zope with data storage in an (Postgre)SQL database. Functionality I am looking for: Things like a detailed address book, call logging, reminders etc... Thanks! Oscar
