I'm happy to announce that GNU Gatekeeper version 4.6 has just been

This version has a few new features as well as bug fixes.

New features:
- least used routing: distribute calls evenly between gateways or MCUs
  (new switch [RasSrv::ARQFeatures] LeastUsedRouting=1)
- ability to log to the Unix syslog instead of the trace file
  (new switch [LogFile] TraceToSyslog=1)
- new authentication module TwoAliasAuth
  this is not very safe, but you can use it with endpoints that do not
  support any password transmission
- new switch [CTI::MakeCall] Bandwidth= to set the maximum bandwidth
  for the calls generated by the GnuGk status port API
- status port command: UnregisterEP <ep-id>
- a number of switches to fine tune TCP keepalives
- new switch to remove load balancers from the call path
  ([RoutedMode] RedirectCallsToGkIP=1)

Bug fixes:
- fixed TCP keepalive for H.460 calls
- fixes to port detection for unregistered calls
- audio fix when GnuGk adds encryption to calls
- many smaller fixes

You can download the new version from
