<br/>
I have just bundeled up the changes and bug fixes of the past 2 years<br/>
and released PTLib 2.10.9.6.<br/>
<br/>
Most notable in this release is working IPv6 on *BSD, macOSX and Solaris<br/>
as well as support for newer compilers and many small platform fixes.<br/>
<br/>
Since PTLib is the foundation for the <a href="https://www.gnugk.org"><s>[url=https://www.gnugk.org]</s>GNU Gatekeeper[/url]</a> and many <a href="https://www.h323plus.org"><s>[url=https://www.h323plus.org]</s>H323Plus[/url]</a> projects, all these improvements get propagated into those projects as well.<br/>
<br/>
- IPv6 support fixed for *BSD, macOSX and Solaris<br/>
- support for newer compiler, eg. gcc 13 and VS2022<br/>
- support for C++-17<br/>
- support for Win64 builds<br/>
- support AIX as platform<br/>
- small OpenBSD fixes<br/>
- other small fixes<br/>

This release also adds features:<br/>
- support for Oracle databases<br/>
- easier cloud deployment with IP detection with STUN<br/>
- better load scaling by mixing proxied with direct mode endpoints in a single gatekeeper<br/>
- Windows 64bit executables with VS2022<br/>
<br/>
<br/>
All changes and additions:<br/>
- enable more runtime hardening flags from OpenSSF recommendation 11/2023<br/>
- fix bug with H.245 address when using ExternalIP= switch without H.460.18/.19<br/>
- auto-detect public IP with ExternalIP=STUN and STUNServer=stun.example.com<br/>
- compiler support for VS2022<br/>
- new database driver for Oracle and new timestamp format 'Oracle'<br/>

H.323, older but robust, offers features like firewall traversal and support for multimedia applications. SIP, more lightweight and flexible, is widely adopted for its simplicity and compatibility with other internet services. While H.323 requires more configuration and has a steeper learning curve, SIP is easier to set up and integrate. Choosing between them often depends on specific network requirements and the complexity of the communication system you aim to deploy.</div>paulejHolographic Videoconferencinghttps://forums.packetizer.com/viewtopic.php?f=31&t=1514&p=3081#p30812022-09-08T03:14:12Z2022-09-08T03:14:12Z<div>Many people have seen the announcement from Cisco related to Webex Hologram, which is an amazing next step in videoconferencing.

This way, I can feed audio into the buffer and have it available whenever a Read request comes from the H323 channel. For the Audio Sink direction I was able to route that audio from the H323 channel's write method. So, now I can create custom H323 channels and route the audio through the network and multiple devices.<br/>

David</div>alcor2022Can we notify H323 channel of available source audio?https://forums.packetizer.com/viewtopic.php?f=46&t=1489&p=3007#p30072022-03-29T14:15:34Z2022-03-29T14:15:34Z<div>Hello,<br/>
<br/>
I have a custom H323Channel class derived from PIndirectChannel. I was able to play a wav file through this channel as in the sample application. Now I have a situation where audio is being provided from the MIC source from NAUDIO and I need to pipe that audio through my custom H323 channel and to other destinations. The issue I am having is that H323 is polling for audio data (calling the read method every 20ms) and I need to sync that with the data I am getting from this other source. Ideally, when I have audio data I want to send through my H323 channel I could trigger an event within H323 and provide the data. This doesn't seem to be available, or I am not aware of how to do that.<br/>
<br/>
So, my solution is to try and implement an event and build a buffer within my own class that can be used to grab data whenever the READ method is called by H323 (I would read data from my buffer, similar to reading a chunk of bytes from an audio file). I will be working on that solution this week, but was wondering if the event notification method was available. I would like to "push" audio data to the H323 source channel rather than have it poll me for data.<br/>
<br/>
The only other option would be to rewrite part of this application to use H323 as the audio source, but then I would need the H323 channel to notify me when source audio is available (so I can broadcast that data elsewhere). I don't like that option because we are using NAUDIO as the source for both our SIP and H323 endpoints. NAUDIO provides data from the MIC that I can then send to SIPSorcery's endpoint/MediaSession and to wherever else. I have not seen an event in H323 I can subscribe to that would provide me audio data from the source (MIC). Is there a way to have H323 send me audio data coming from the local source device?<br/>

I was able to place a call to my C# application using the H323Plus wrapper that I am building (I called my endpoint using the Ekiga softphone). Next step is to place an outbound call and continue developing the wrapper functionality. I am also generating events that can be consumed by the C# application.<br/>

<br/>
I believe I have successfully integrated H323 into my wrapper DLL. I am able to create a global Process class, and call the PProcess::Current().getLibVersion() method from one of my reference classes instantiated in my C# application. Next step is to setup an endpoint via the C# app and see if I can get it listening for incoming calls. Then I'll implement a MakeCall method to try and place a call to an Ekiga endpoint.<br/>
<br/>
Basically, in my main wrapper ref class, I placed this:<br/>
<br/>
extern BaseApp _theApp;<br/>
<br/>
Then in the BaseApp class, which includes a class based on PProcess, I created a global instance in the cpp file:<br/>
<br/>
BaseApp _theApp;<br/>
<br/>
My BaseApp class looks like this (in BaseApp.h):<br/>
<br/>
<B><s>[b]</s><COLOR color="#0000FF"><s>[color=#0000FF]</s>class BaseApp<br/>

<br/>
~BaseProcess() {}<br/>
<br/>
void Main() {}<br/>
} _baseProcess;<br/>

<br/>
I am working on a VC++ wrapper for H323Plus (based on compiled H323Plus.lib and ptlibs.lib). There will be a C# executable that references the wrapper DLL to use H323Plus features. Before I go much further I would like to understand the function of the PProcess and PCREATE_PROCESS. There is some internal initialization happening, but this is basically what I have so far:<br/>
<br/>
<B><s>[b]</s> PCREATE_PROCESS(BaseProcess);<br/>
<br/>
/* This is what PCREATE_PROCESS is doing<br/>
int main(int argc, char **argv, char **envp)<br/>
{<br/>
BaseProcess *pinstance = new BaseProcess();<br/>
pinstance->PreInitialise(argc,argv,envp);<br/>
int terminationValue = pinstance->InternalMain();<br/>
delete pinstance;<br/>
<br/>
return terminationValue;<br/>
}<br/>
*/<br/>
<br/>
BaseProcess::BaseProcess()<br/>
: PProcess("H323Plus", "Wrapper", MAJOR_VERSION, MINOR_VERSION, BUILD_TYPE, BUILD_NUMBER, true)<br/>
{<br/>
<br/>
endpointp = NULL;<br/>
}<br/>
<br/>
BaseProcess::~BaseProcess()<br/>
{}<br/>
[/b]</B><br/>
<br/>
Notice the last parameter in the PProcess arguments of "true". From what I gather, this is supposed to indicate that the process is used in a library versus an executable. I've made a comment block which shows what the PCREATE_PROCESS expands to. Basically, I am not sure how to use this PProcess object in a class library. What I would like to do is create the process instance as shown in this block, but create it when I instantiate my H323 wrapper class from the C# module. In examples I have seen, the main routine for the Process is setting up a loop or a terminationSync.Wait(). Is it required to have a process with a continually running thread (the main() routine)? I know that a Process instance is needed, as some methods are looking for Process::Current(). Looking for some guidance on how to implement this in a class library vs. directly in an executable.<br/>

I've edited this post a few times, as I make progress in my analysis. My wrapper code is just a few lines to try and prove I can do it, so I haven't bothered to put it up in a Repo. <br/>
<br/>
I did some rearranging of the includes (based on what I could see in the simple sample app, and then I got these errors in h4601.h:<br/>
<br/>
c:\h323work\h323plus-1_27_2\include\h460/h4601.h(1069): error C2143: syntax error : missing ')' before 'generic'<br/>

<br/>
The line in question:<br/>
<B><s>[b]</s>/** Build a FeatureSet from the contents of a generic data field.<br/>
*/<br/>
H460_FeatureSet(const H225_ArrayOf_GenericData & generic);<br/>
[/b]</B><br/>
<br/>
I finally discovered that the issue may be that the compiler is thinking the code in these header files is using reserved keywords where it shouldn't be. For example; I changed the "generic" parameter name in the above function declaration to "genericA". When I did that all of the above errors disappeared and the project compiled successfully., so the modified header file code looks like this:<br/>
<br/>
<B><s>[b]</s> H460_FeatureSet(const H225_ArrayOf_GenericData & genericA);[/b]</B><br/>
<br/>
I suspect this was the same issue in the Thread.h file, but I haven't gone back and looked. Right now it doesn't even show up in the code/list of external references. Don't know if that is good or bad.. just that perhaps it is not needed.<br/>
<br/>
I'll be back, I'm sure, with additional questions about using the libraries and getting my first project working.<br/>

since you can build H323Plus and only in your own code you get these compile errors, my guess would be that you might not be including the PTLib headers in the right order or maybe only a few internal ones ?<br/>

I have downloaded and managed to build static ptlibs.lib and h323plus.lib. I used VS2017 to load the VS2010 solutions. I left the Windows SDK version at 8.1 and Platform Toolset to V100. What version of the Windows SDK is compatible? It was difficult to find any instructions for building the projects, but I think I got all the pieces hooked up. Now, the challenge is that I want to create a wrapper DLL in VS2017 C++ so I can use features in C#. So, in my wrapper code I am able to access classes/methods from H323Plus. Everything was looking good until I went to build the wrapper project. I am getting 14 compiler errors in the Thread.h and h4601.h header files:<br/>

I have NO IDEA what is causing these errors. The first error in the list is referring to this statement in Thread.h:<br/>

);<br/>
<br/>
It was really frustrating to make it so far in the process only to be stopped by these errors in header files included in the source download.<br/>
<br/>
I would like to find a step-by-step set of instructions for how to compile the current source code provided on H323plus.org using Visual Studio 2017. There is nothing available anywhere (the frequently mentioned <a href="http://www.voxgratia.org/documents.html">http://www.voxgratia.org/documents.html</a> no longer exists). Has anybody been able to download the current source and build the PTLib and H323Plus projects on Windows with VS2017/2010? Note that TECHNICALLY I have built the projects, but I am not 100% sure they were built correctly.<br/>
<br/>
My end goal is to create a C# application that can create a basic H323 endpoint to talk to another H323 device.<br/>
<br/>
Any help would be greatly appreciated.<br/>

This release has a number of new features as well as some important bug<br/>
fixes.<br/>
<br/>
Whats new ?<br/>
<LIST><s>[list]</s>
<LI><s>[*]</s> LRQ loop detection to optimize calls flows between multiple<br/>
neighbor gatekeepers<br/>
This new feature has the potential to significantly reduce the load<br/>
on all gatekeepers and prevent "LRQ storms".</LI>
<LI><s>[*]</s> new routing policy to set call destinations by querying HTTP<br/>
or REST servers, see [Routing::Http]</LI>
<LI><s>[*]</s> much improved support for SNMP</LI>
<LI><s>[*]</s> important bug fix for TLS encryption of signaling channels</LI>
<LI><s>[*]</s> important bug fixes for H.460.18 (for H.245 tunneling and for<br/>
multi-homed servers)</LI>
<LI><s>[*]</s> performance optimization: this version can handle 5-10% more proxied<br/>
calls on the same hardware</LI>
<LI><s>[*]</s> performance optimization: re-authenticate lightweight, additive<br/>
registrations only when new aliases differ<br/>
This significantly reduces the load on password databases.</LI>

I am trying to integrate H.323 Plus into my project, for some particular reason I need to have a simple setup message without TCS, just waiting for remote peer's response with TCS in connect message to decide which media capabilities should be used.<br/>
But what I found is that no matter if I enable/disable "faststart" flag, I still can see TCS and MSD in setup message, the only difference is that when using "faststart", "OpenLogicalChannel" can be seen in setup message.<br/>
I'm wondering if it is because H323Plus was optimized using "Parallel H.245" by default? If so, how can I disable this "Parallel" feature?<br/>

<br/>
The main new feature in this release is H.245 multiplexing.<br/>
Together with the long supported RTP multiplexing it allows GnuGk to<br/>
handle a large amount of calls from H.460 endpoints using just 5<br/>
ports total.<br/>
<br/>
Whats new ?<br/>
<br/>
- support for H.245 multiplexing with H.460.18:<br/>
[RoutedMode] EnableH245Multiplexing=1, H245MultiplexPort=1722<br/>
- improved interop with Lifesize Icon (H.235), Scopia VC240 (H.460.18)<br/>
and Yealink Mobile (H.460.19)<br/>
- improved detection of neighbor gatekeeper availability<br/>
- public IP detection for Google Cloud<br/>
- new feature to let GnuGk send an event if port detection fails<br/>
<br/>
There were also a number of bug fixes, please see changes.txt or the<br/>
blog post:<br/>
