Callstats collects and displays call statistics for Siemens HiPath OpenOffice ME in a pretty Web interface. It may work with other Siemens HiPath devices (probably Hipath 3000). With some modifications, it could be adapted to your own system. It has 3 parts: -tcp->text log (via netlog); text log->sqlite database (PHP script); and a Web interface to the SQLite database (PHP). It has been tested without problems in a 50-user installation fulltime since 2009.
