GNU Gatekeeper 4.6 is out

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

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
  • new 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 (important!)
  • 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
https://www.gnugk.org/h323download.html


Please see the full change log below.
