Take a look at www.oracle.com. Oracle magazine lists my company as one out of three Oracle Certified Partners, which has announced a product based on 11g:
GIP will use Oracle Database 11g in Xyna Service Factory, GIP's integrated platform for the development, production, and lifecycle management of IP-based telecommunication services. Specifically, Oracle Database 11g is the basis for two elements of the Xyna Service Factory platform: Xyna Service Warehouse, a subscriber-centric active warehouse, and Xyna Intelligence, a subscriber touchpoint management system. GIP serves leading German and international companies in the telecommunications, information, media, and entertainment sectors.
