A great deal of corporate data is buried in network devices --- such as PBX messaging/email platforms, and data networking equipment --- where it is difficult to access and modify. Typically, the data is only available to the device itself for its internal purposes and it must be administered using either a proprietary interface or a standard protocol against a proprietary schema. This leads to many problems, most notably: the need for data replication and difficult interoperation with other devices and applications. MetaComm addresses these problems by providing a framework to integrate data from multiple devices into a meta-directory. The system allows user information to be modified through a directory using the LDAP protocol as well as directly through two legacy devices: a Definity (R) PBX and a voice messaging system. In order to prevent data inconsistencies, updates to any system must be reflected appropriately in all systems. We also discuss implementation details and experiences.
