OpenCALEA is a project intiated by Merit Network Inc. whose goal is to develop simple OpenSource based tools that can help the Internet Service Provider community to meet their CALEA compliance needs.
The project was started as an attempt to gain a technical understanding of the proposed standard and develop an implementation that would serve as a reference model. Community contibutions to the project are encouraged and greatly appreciated.
There is considerable confusion regarding CALEA and what it means to be CALEA compliant. It is upto individual organizations to decide for themselves what their obligations are regarding CALEA. OpenCALEA provides a community based implementation framework for helping with CALEA compliance.
