Hi all: Does H.323plus support H.460.6 now? Is there any tools to simulate H.460.6? thanks George _________________________________________________________________ MSN 中文网，最新时尚生活资讯，白领聚集门户。 http://cn.msn.com

Need tested source code to run an MCU
by Shahzad Abid 22 Sep '08

22 Sep '08

Dear All I am trying since last week to run an openmcu on Centos5 and I have tried almost all the combination of source code available at h323plus.org web site and at source forge.net I need help to install h323plus + openmcu to stablish a video conferacing room. I am successfull installing openh323 + openmcu v2.2.1 on ubuntu but users can't see video but they can hear voice although openmcu's statistics show that clients are Rx/Tx video frames but there is not video at any end. Regards, Shahzad Abid

H323Transport::HandleFirstSignallingChannelPDU crash when connection is NULL
by Nir Soffer 21 Sep '08

21 Sep '08

In H323Transport::HandleFirstSignallingChannelPDU, if NULL connection is returned from endpoint.OnIncomingConnection, the code try to send a release complete to the other side. However, line 1292 is not going to work (the connection is NULL): releaseComplete.Write(*this,*connection); To fix this, I added a Write method which does not accept a connection. Note that the new method duplicate the code from the version that accept a connection - I did not have to time to do it properly. The patch is created against version 1.20.2-alpha2. I verifyed that the issue still exists in the trunk. http://h323plus.cvs.sourceforge.net/h323plus/h323plus/src/transports.cxx?vi…

OpenMCU and XMeeting
by Michael Miller 19 Sep '08

19 Sep '08

I'm having trouble with XMeeting and OpenMCU. XMeeting connects fine intially, but if another h.323 client joins the session, XMeeting disconnects and OpenMCU crashes. Here's what I get at the console for OpenMCU: *** glibc detected *** openmcu: free(): invalid pointer: 0x098912c8 *** ======= Backtrace: ========= /lib/libc.so.6[0xb49ac1]

Re: [h323plus] H323 error codes

Thanks a lot Robert for your prompt response. I got confused with your answer. Actually I posted 2 questions so the answer if of which question. The 2 questions are Actually I am looking for error codes in H323 protocols. 1) In H225/Q931 what could be the error codes. Is these error codes comes along with the last message "Release complete message" ? are in between the call.I am able to find these kind of codes specifically in SIP with the response messages with their numbers(Ex:400,500,..),similarly the case with the MGCP protocol.But,I am very much confused with the H.323. 2)What could be the case with the H.245 protocol.

H323 error codes

Hi all, In Q931 protocol is it necessary that the cause code will come in last message. Does H245 contains the cause codes. Thanks Mayank Jain

Cosmetic issues PTLib v2.0.1 with VS2008-SP1

Hello Reporting some cosmetic issues during compiling PTLib on VS2008-SP1. The files: vsdl.cxx pvfiledev.cxx pstun.cxx Have the macro '#define P_FORCE_STATIC_PLUGIN', the VS compiler outputs: 1>..\..\ptclib\{one of above} : warning C4603: 'P_FORCE_STATIC_PLUGIN' : macro is not defined or definition is different after precompiled header use 1> Add macro to precompiled header instead of defining here 1> ..\..\ptclib\{one of above} : use of precompiled header But the <ptlib/pluginmgr.h> includes <ptlib/plugin.h>, the later already define 'P_FORCE_STATIC_PLUGIN' when compiling under _WIN32. So remove or comment the #define P_FORCE_STATIC_PLUGIN from: vsdl.cxx pvfiledev.cxx pstun.cxx //============================ sockets.cxx The '#include <ptlib.h>' is the pre-compiled header and MUST come 1st so, changing '#include <ptlib.h>' to come before '#ifdef __NUCLEUS_PLUS__' >>>before: #ifdef __NUCLEUS_PLUS__ #include <ConfigurationClass.h> #endif #include <ptlib.h> >>>after: #include <ptlib.h> #ifdef __NUCLEUS_PLUS__ #include <ConfigurationClass.h> #endif //============================ Error: sphelper.h(1170) GetUserDefaultUILanguage(): identifier not found Configure is using c:\program files\microsoft sdks\windows\v6.0a\ for Located Speech API compile without speech support. -- ----- Jogue RPG, alimente o lado criativo!

Registering with the GnuGK - continued

Hard coding the authenticator.Enable (as shown bellow) solves the registration problem. Obviously this is not good - any ideas why authenticator.IsCapability returns the wrong result in the "simple" sample application ? BOOL H323Gatekeeper::OnReceiveGatekeeperConfirm(const H225_GatekeeperConfirm & gcf) { if (!H225_RAS::OnReceiveGatekeeperConfirm(gcf)) return FALSE; PINDEX i; for (i = 0; i < authenticators.GetSize(); i++) { H235Authenticator & authenticator = authenticators[i]; if (authenticator.UseGkAndEpIdentifiers()) authenticator.SetRemoteId(gatekeeperIdentifier); } if (gcf.HasOptionalField(H225_GatekeeperConfirm::e_authenticationMode) && gcf.HasOptionalField(H225_GatekeeperConfirm::e_algorithmOID)) { for (i = 0; i < authenticators.GetSize(); i++) { H235Authenticator & authenticator = authenticators[i]; authenticator.Enable( TRUE /*authenticator.IsCapability(gcf.m_authenticationMode, // <<<< This makes it work gcf.m_algorithmOID)*/); PTRACE(4,"RAS\tAuthenticator " << authenticator.GetName() << (authenticator.IsActive() ? " ACTIVATED" : " disabled")); } }
