H323connection AnsweringCall issue
by Ankur Deep Jaiswal 09 Jun '15

09 Jun '15

Hi, I am facing a strange problem, on H323Connection::OnAnswerCall i am returning AnswerCallPending. and after sometime i call H323Connection::AnsweringCall with AnswerCallNow . but what happens now and then, i would say every second call, is that, even if i call H323Connection::AnsweringCall, the PDU does not seem to have been sent. the connection then proceeds to be in a vegetative state. when i disconnect the connection and reconnect it, it proceeds to connect successfully. i am not creating any extra threads in the system. the logic for H323Connection::AnsweringCall runs on the main thread. i am using h323plus version 1.26.5. regards -- Ankur Deep Jaiswal

h323plus - GetConnectedNumber
by Tarmo Aia 10 May '15

10 May '15

Hi! I dealt with problem, that user picked up the call from the hunt group but the call manager did not changed the Remote Party number but only affected the Q931 connect message with IE Connected Number property. I added a little function called SetRemoteConnectedNumber to h323.cxx to read it and change to the remote party number during answer (connection). Not sure this is the 100% right way but I would contribute this small line of code if You have interest. Tested working with Avaya Call manager 6.x Best regards, Tarmo Aia

Nagios plugin for H.323
by Jan Willamowius 05 Feb '15

05 Feb '15

Hi, I have released a Nagios plugin to monitor H.323 devices (any H.323 gatekeeper or gateway, it doesn't have to be GnuGk). http://www.gnugk.org/nagios-h323.html It doesn't just check if the device listens to a port, but sends a real H.323 message (GRQ or LRQ) and checks if a well formed message comes back.

GNU Gatekeeper 3.8 is available
by Jan Willamowius 05 Jan '15

05 Jan '15

I am pleased to announce a new release of the GNU Gatekeeper, version 3.8, now available from http://www.gnugk.org/h323download.html. Please see the attached notes for details. This release includes source code suitable for (Linux, Windows, MacOS, FreeBSD, NetBSD, OpenBSD and Solaris) and executables for Linux. -- Jan Whats new in GnuGk 3.8 ? In response to the current wave of H.323 spam / hacking GnuGk 3.8 has a number of improvements to security related features and older versions should be updated. - endpoint IDs are now completely random and not as easily guessable as they were before - GnuGk is now using better random numbers in security relevant places - new authentication modules using LUA scripts called LuaAuth - new switch [RasSrv::ARQFeatures] CheckSenderIP=1 to make sure ARQs come from the same IP as the initial registration - FileIPAuth is now able to check ARQ messages - AliasAuth updated to work with H.460.18 endpoint - PrefixAuth was extended to support unregistered calls - SQLAuth can now operate on SrcInfo fields using %{SrcInfo} - improvements to the addpasswd utility for the new web interface Other new non-security related features include: - The CatchAll policy now rewrites the destination alias which makes it easier to send CatchAll calls to MCU rooms. - You can now filter out whole capability classes, eg. all video or H.239 capabilities if some of your endpoints have trouble handling them - A new switch [Gatekeeper::Main] MinH323Version= lets you set the H.323 version GnuGk identifies itself as using (up to the latest version 7). This is mainly to deal with endpoint that switch features when they believe they are talking to older endpoints (which one shouldn't be doing...) - a number bugs and crashes fixed Download from http://www.gnugk.org/h323download.html -- Jan Willamowius, Founder of the GNU Gatekeeper Project EMail : jan(a)willamowius.de Website: http://www.gnugk.org Support: http://www.willamowius.com/gnugk-support.html Relaxed Communications GmbH Frahmredder 91 22393 Hamburg Geschäftsführer: Jan Willamowius HRB 125261 (Amtsgericht Hamburg) USt-IdNr: DE286003584

Re: [h323plus] [Openh323gk-users] Using LibreSSL instead of OpenSSL with GnuGk / H323Plus / PTLib
by Jan Willamowius 29 Jul '14

29 Jul '14

It would be nice if PTLib would do a pgk-config check for "openssl" or "libressl" to activate the OpenSSL code. I simply named the pgk-config file for LibreSSL "openssl.pc" to work around that. To use GnuTLS for the H.323 media encryption in GnuGk and H323Plus, PSSLxxx wrappers won't help. The OpenSSL compatibility mode of GnuTLS also isn't enough. regards, Jan Robert Jongbloed wrote: > Excellent! > > Are there any tweaks to the configure.ac that should happen to find > LibreSSL? > > > And re GnuTLS, the whole point of the PSSLxxx class wrappers in PTLib > was to allow for use of other API's to OpenSSL/LibreSSL.

Using LibreSSL instead of OpenSSL with GnuGk / H323Plus / PTLib
by Jan Willamowius 29 Jul '14

29 Jul '14

Hi, with the bugs recently found in OpenSSL, there is some concern how many more issues still lurk in the old and crufty OpenSSL code. There is a great effort by some OpenBSD developers to fork OpenSSL into "LibreSSL" (www.libressl.org) and clean up the code while keeping the public interface stable. I did a quick check and can report that GnuGk / H323Plus / PTLib compile well with LibreSSL instead of OpenSSL. All I had to do was provide a pkg-config file. So now we have a choice which library to use. I used LibreSSL Portable 2.0.3 for my test. Another interesting project would be to use GnuTLS as a replacement, but thats going to require a number of code changes on our side.
