If not, what are the advantages of using TCP signalling over UDP, aside from it being reliable (considering UDP packets doesn't exceed the UDP size limit for each message sent, if it's even possible with H323 messages) ? Another question, is it possible to include generic messages within the signalling messages (setup, process, alert, connect, facility etc) just as we can with the h.245 OLC messages? Thanks in advance for your help and suggestions. Josh C.

It works when compiling against the uninstalled version of ptlib because it has a file ~/src/ptlib-2.10.1/revision.h ( we unpack in ~/src ). We solve the problem by zapping the offending include. The second, minor problem, is the "#define PTLIB_SVN_REVISION SVN_REVISION" which fails when zapping the include, we zap this too and it works. I think BOTH lines should be deleted, they seem like some kind of testing stuff. If we do it after installing every h323plus code we compile builds without any problem.

Wen i make calls to or receive calls from myphone2 or the lite version of spranto, I can hear incoming audio but the simpleplus doesn't seem to be transmitting any sound regardless of which machine i've tried on (All windows 7 / Vista). I tried debugging a little to determine the cause but so far no luck. I've also had issues compiling the code due to unresolved external errors coming from the h460p.cxx but have not really looked much into it and for it to work I had to disable H323_H460P. Your help would be greatly appreciated. Josh </pre> J.C Mercier 2012-03-26T00:01:57 http://comments.gmane.org/gmane.comp.telephony.h323plus/909 <pre>Hi all, I'm new on h323plus. First of all I need to compile H323plus with the H264 plugin. I searched a document or any tutorial on how to do it, but didn't find any. Can anyone help me, please? Is there any documentation on how to compile H323 in general? Thank you! Talita </pre> Talita Ferraz Roberti 2012-03-15T13:58:13 http://comments.gmane.org/gmane.comp.telephony.h323plus/904 <pre>Hi all, I'm working on a h323-sip gateway with video (H264) support and I'm facing some problems. I'm new with H323plus and with h323 protocol itself (I'm learning as I go) so excuse me if I say something stupid. First of all, I believe that the stack can be used to build a gateway but it seems that it's more focused on terminals. Am I right? So is it possible or not to build a gateway using it? Second, there is no native support for H264. The documentation shows the class hierarchy. For audio we have, for instance, H323Cabability -&gt; H323RealTimeCapability -&gt; H323AudioCapability -&gt; H323_G711Cabability but we don't have H323Cabability -&gt; H323RealTimeCapability -&gt; H323VideoCapability -&gt; H323_H264Cabability. I tried to create this one, extending from H323Cabability -&gt; H323RealTimeCapability -&gt; H323VideoCapability -&gt; H323GenericVideoCabability and then I discovered that I would need to override a function called CreateCodec to return a codec that handles the video. But I don't want to handle the RTP media. I just want to put H264 in the terminal capability set and establish a connection in a way that the H323 and SIP terminals can exchange the media directly. I've heard about a H264 plugin but it seems that it is for handling the media, so I don't know if it fits my purpose. How can I achieve this? Is there any plan to support H264 natively on H323plus? Also I need to get the remote RTP port. The only way I found to do this is trough H323Connection::OnStartLocicalChannel but this is called after a channel to handle the data is created and again, I don't want to handle the RTP data. I appreciate any help. Thanks. </pre> Diego Carvalho 2012-03-13T17:04:50 http://comments.gmane.org/gmane.comp.telephony.h323plus/903 <pre>Guys Apologies for cross posting Over the last couple of months Jan and I have been committing a lot of H.460 NAT support into H323plus and GnuGk . H.460.18/.19, Multiplexing, Traversal Zones and H.460.23/.24/.24A/.24B and just recently H.460.17. I have written with Jan's assistance an ordinary person guide to NAT, the types of NAT and the logic behind H.323 NAT Traversal solutions. It briefly explains exactly what all these standards mean and how they fit together to provide a complete NAT Traversal solution. h323_nat_fw_solution.pdf &lt;http://hive.packetizer.com/users/h323forum/specifications/h323_nat_fw_solut ion.pdf&gt; Simon </pre> Simon Horne 2012-03-12T18:15:33 http://comments.gmane.org/gmane.comp.telephony.h323plus/898 <pre>Hi all, If i may first note, I've compiled the latest h323plus with no problem, but when i go to compile the simpleplus program, it gives an unresolved error for H46019UDPSocket::GetPeerAddress(...). This happens because H323_H46024A and H323_H46024B are disabled and GetPeerAddress is defined within H323_H46024A but declared within H323_H46019M. I did a minor work around and it now compiles fine. Another issue I came upon, when I initialize UPNP during the h323 initialization, during the UPnPThread::TestMapping() function call, it manages to map both ports (11000 and 11001) but after calling RemoveMap(extPort,true); and RemoveMap(extPort+1,true), only 11001 is removed and not 11000. I tested this with different port range and it produces the same results (one unmapped and not the other). Is this supposed to be the case or is something wrong somewhere? Although, after closing the program, both ports are unmapped successfully. But another problem that happens every time I close the program is a memory access violation at; ~IxNATNumberOfEntriesCallback() { delete m_pointer; } from interface IxNATNumberOfEntriesCallback : public INATNumberOfEntriesCallback Any reason why this could be the case? Lastly, when upnp is initialized, making a call doesn't seem to open and map the ports at all. What else should be done aside from initializing upnp? Your help and suggestions will be greatly appreciated.

Any info or other possibilities/approach will be greatly appreciated Thanks Josh </pre> J.C Mercier 2011-12-26T07:10:00 http://comments.gmane.org/gmane.comp.telephony.h323plus/883 <pre>Hi all, looking through the h323plus code, I noticed it supports multiplexing for H.460.19. Just a few questions; 1. Does H323plus also support RTP multiplexing without the need for h.460.19 (direct endpoint to endpoint)? 2. If it doesn't support endpoint to endpoint multiplexing, does limiting RTP ports to only a few ports such as 10 to 12 (i.e. 3000 - 3010) opened port always remain in that range or will this produce any side affects when making a lot of calls? 3. With multiplexing support for H.460.19, is it 2 ports; 1 bi-directional port for audio and 1 bi-directional port for video? is there a third port for RTCP (QoS)? 4. Is sending/receiving RTCP/QoS mandatory for H.323 systems? What affects are there if this is not enabled?

I've downloaded the latest ptlib, h323plus core and applications from http://www.h323plus.org/source/. I started with a virgin install of Ubuntu 10.04 and installed dependent libs as necessary. Which version of ffmpeg works best with the plugins? apt-get retrieves ffmpeg 0.5.1. everything compiles fine and when I point PWLIBPLUGINDIR to OPENH323DIR/plugins openam lists all the codecs I expect to see - including H263. However, when I connect my video endpoint to it the video is freezes on what appears to be the first frame. I've tried later versions of ffmpeg from ffmpeg.org and libav from libav.org (recompiling h323plus, the plugins and openam after each ffmpeg change) but then openam doesn't list H263 in its list of codecs - only H261. The configure script indicates libavcodec and h263 is available for every combination I've tried. So, what's the secret to building openam with the H263 codecs? What version of ffmpeg must I use? Any help is greatly appreciated! PS: my apologies for first accidentally sending this to open323gk-users.
