07 Jan '19

Hi, I have released GNU Gatekeeper version 5.1. You can download it from https://www.gnugk.org/h323download.html The main new feature in this release is H.245 multiplexing. Together with the long supported RTP multiplexing it allows GnuGk to handle a large amount of calls from H.460 endpoints using just 5 ports total. Whats new ? - support for H.245 multiplexing with H.460.18: [RoutedMode] EnableH245Multiplexing=1, H245MultiplexPort=1722 - improved interop with Lifesize Icon (H.235), Scopia VC240 (H.460.18) and Yealink Mobile (H.460.19) - improved detection of neighbor gatekeeper availability - public IP detection for Google Cloud - new feature to let GnuGk send an event if port detection fails There were also a number of bug fixes, please see changes.txt or the blog post: https://blog.gnugk.org/2019/01/gnu-gatekeeper-5-1.html Enjoy! -- Jan Willamowius, Founder of the GNU Gatekeeper Project EMail : jan(a)willamowius.de Website: https://www.gnugk.org Support: https://www.willamowius.com/gnugk-support.html Relaxed Communications GmbH Frahmredder 91 22393 Hamburg Geschäftsführer: Jan Willamowius HRB 125261 (Amtsgericht Hamburg) USt-IdNr: DE286003584

Dear H323plus Team: I think I need some help that when I use the simph323,it can't use the H.264 in my ubuntu 16.04,and the sound device is NO Audio . I wanted to found the solutions by Google ,but I can only found I need to install libavcodec and alsa .so I do it. And the sound output device can be found ,but the sound input device still NO Aduio. In my ubuntu 16.04 ,I had install all about alsa ,and I install libavcodec-dev and ffmpeg ,but it doesn't work. The error message is as follows Sound output device: "alsa_output.pci-0000_02_02.0.analog-stereo" Sound input device: "Null Audio" checking for LIBAVCODEC... yes configure: libavcodec stack align hack disabled checking for h263p_encoder in -lavcodec... no checking for h263p_encoder in -lavcodec... (cached) no checking for mpeg4_encoder in -lavcodec... no checking for h264_decoder in -lavcodec... no

H.239 bug fixes and improved test tools
by Jan Willamowius 25 Jul '18

25 Jul '18

Hi, if you are using H.239, you should update to the latest code from Github. A number of bugs have been fixed in the H.239 code recently. If you still see issues, please let me know. https://github.com/willamowius/h323plus As part of the H.239 testing, I also added H.239 support to the call generator (--h239enable) as well as RTP fuzzing (--fuzzing). Its amazing how many commercial H.323 endpoints crash when you apply some RTP or RTCP fuzzing. ;-) https://github.com/willamowius/callgen323 Regards, Jan -- Jan Willamowius, H323Plus maintainer EMail : jan(a)willamowius.de H.323 Support: https://www.willamowius.com/h323plus-support.html Relaxed Communications GmbH Frahmredder 91 22393 Hamburg Geschäftsführer: Jan Willamowius HRB 125261 (Amtsgericht Hamburg) USt-IdNr: DE286003584

OpenSSL 1.1
by Jan Willamowius 27 Apr '18

27 Apr '18

Dear community, currently H323Plus depends on OpenSSL 1.0 to enable the full functionality. Adapting password checksums to the OpenSSL 1.1 API was easy and is already in the repository, but moving the media encryption code to 1.1 is very hard. Many Linux distributions are moving to OpenSSL 1.1 and its starting to get complicated to build GnuGk with media encryption since other shared libraries depend on OpenSSL 1.1 now. I'm looking for sponsors to help fund the development work to fully move H323Plus and all the applications that depend on it (GnuGk etc.) to OpenSSL 1.1. If you or your company can help. Please send me an email.

GNU Gatekeer 4.9 released
by Jan Willamowius 05 Apr '18

05 Apr '18

Hi, I have just released GNU Gatekeeper version 4.9. This version has new features and a few bug fixes. You can download it from https://www.gnugk.org/h323download.html Whats new ? We have 2 new accounting modules: HtttpAcct and AMQPAcct that allow you to send accounting events via HTTP GET or POST to a web service or push them into a RabbitMQ queue. There are also many new accounting placeholders that you can use with any of the accounting modules and there is a new accounting event 'reject' to track calls rejected with ARJ that went unnoticed before. The new RTP inactivity checking allows you to drop calls if there wasn't any RTP activity for a defined amount of time. GeoIP authentication has been significantly updated to support all RAS and all Q.931 messages and to support the new Maxmind database format (GeoIP2). There were also a few bug fixes: - BUGFIX(ProxyChannel.cxx) fix crash while handling RTP packets - BUGFIX(RasTbl.cxx) fix disconnecting unregistered endpoints - BUGFIX(RasSrv.cxx) fix crash in some Avaya endpoints when receiving GCF with a gatekeeperIdentifier - BUGFIX(RasSrv.cxx) fix crash when using IPv6 - BUGFIX(ProxyChannel.cxx) fix handling of CloseLogicalChannel Enjoy! -- Jan Willamowius, Founder of the GNU Gatekeeper Project EMail : jan(a)willamowius.de Website: https://www.gnugk.org Support: https://www.willamowius.com/gnugk-support.html Relaxed Communications GmbH Frahmredder 91 22393 Hamburg Geschäftsführer: Jan Willamowius HRB 125261 (Amtsgericht Hamburg) USt-IdNr: DE286003584

GNU Gatekeeper 4.8 released
by Jan Willamowius 17 Jan '18

17 Jan '18

Hi, I have just released GNU Gatekeeper version 4.8. This version has many new features. You can download the new version from https://www.gnugk.org/h323download.html Overview: New maintenance mode: When you need to take down your GnuGk server (eg. for an OS update), you can switch GnuGk to maintenance mode where it will only allow ongoing calls to finish and automatically redirects all idle endpoints to an alternate GnuGk server. The status port command is "MaintenanceMode <alternate IP>". Detailed information about ongoing calls: You can now display lots of information about each ongoing call (codecs, bandwidth used, IPs etc.). The web interface has been extended to to show this information. See https://www.gnugk.org/images/web7.jpg Easier installation on AWS and inside docker containers. You can now let GnuGk automatically detect the public IP of your AWS server, even from within a docker container. You can also automatically insert your public/external IP into your trace file names to store logs from many servers in the same directory. Extended API: Call routing with external applications has been expanded. You can now set the display names for participants and desired reject codes on the status port. You can also access the vendor information of all registered endpoints. The web interface has been extended to provide this information, too. HttpPasswordAuth has been greatly extended to fetch password information from backend servers. We now use curl to support https and you can add many new placeholders in your queries. Extended screening and rewriting of display names and calling party names. Important bug fixes: Multiplexed RTP is now much more robust and password authentication to parent gatekeepers has been fixed. There are also interop fixes for TCP keep-alives. Please see the full change log below for more details. Changes from 4.7 to 4.8 ======================= - HttpPasswordAuth: support https and add new placeholders - PrintAllRegistrationsVerbose now also shows the endpoint vendor - new status port command: MaintenanceMode - new status port command: PrintCallInfo - allow placeholder %{gkip} and %{external-ip} in [LogFile] Filename= - fetch AWS public/elastic IP if ExternalIP=AWSPublicIP - new commandline switch: -e / --externalip - extend status port command RouteReject to set reject reason - extend status port commands RouteToAlias, RouteToGateway etc. to set display IE for calling and called - new switch: [LogFile] DeleteOnRotation=1 to delete the old logfile when rotating instead of renaming it - new switches: [RoutedMode] AppendToCallingPartyNumberIE= / PrependToCallingPartyNumberIE= to add any string before or after the calling party number IE when ScreenCallingPartyNumberIE=RegisteredAlias - when [RoutedMode] ScreenCallingPartyNumberIE= is set to RegisteredAlias, GnuGk sets calling party number IE to the registered alias (forced screening) - delete DisplayIE when [RoutedMode] ScreenDisplayIE=Delete - new switch [Endpoint] Authenicators= - new default: [RoutedMode] GnuGkTcpKeepAliveMethodH225=EmptyFacility - new default: [RoutedMode] H460KeepAliveMethodH225=EmptyFacility for Cisco interop - new setting "None" for keep-alive methods - BUGFIX(ProxyChannel.cxx) fix bugs in H.460.19 RTP multiplexing - BUGFIX(ProxyChannel.cxx) don't send H.460 keep-alive to non-H.460 party when calling H.460 party - BUGFIX(Routing.cxx) show called port in RouteRequests (as documented) - BUGFIX(GkClient.*) fix password authentication with parent - BUGFIX(Routing.cxx) remove semicolon and pipe chars from vendor string in RouteRequests - better handling of IPv6 GRQ without RAS address - BUGFIX(ProxyChannel.cxx) turn off encryption proxy if DH key is negotiated, but TCS doesn't contain any H.235 entries - BUGFIX(ProxyChannel.cxx) fix running in proxy mode on FreeBSD when one Home IP is set - BUGFIX(ProxyChannel.cxx) fix DisableSettingUDPSourceIP=1 for Windows, NetBSD, OpenBSD and Solaris - BUGFIX(yasocket.cxx) fix LARGE_FDSET for NetBSD, OpenBSD and Solaris -- Jan Willamowius, Founder of the GNU Gatekeeper Project EMail : jan(a)willamowius.de Website: https://www.gnugk.org Support: https://www.willamowius.com/gnugk-support.html Relaxed Communications GmbH Frahmredder 91 22393 Hamburg Geschäftsführer: Jan Willamowius HRB 125261 (Amtsgericht Hamburg) USt-IdNr: DE286003584
