Blocking of TCS and MSD messages
by Mark Fawcett 08 Feb '11

08 Feb '11

All, I am making an outgoing call from h323plus to an SJPhone endpoint using fast-start. All seems well, the h323plus sends the setup message with fs (specifying g711alaw) and the remote end responds with callProceeding / alerting / connect. The connect message contains a fast-start OLC itself and all is good. However, the h323plus stack then issues TCS and MSD messages. We are being asked if these can be stopped (my understanding is that Fast-Start allows for connectivity to be made with just the setup & connect messages)? Many thanks for your time.

Question regarding g711Alaw codec and preferred packet size
by Mark Fawcett 08 Feb '11

08 Feb '11

All, I am struggling with what I suspect is a very simple question: How do I make an outgoing call via h323 specify 20ms packets for the g711Alaw codec instead of the default 30ms? Many thanks, Mark Mark Fawcett Managing Director +44 (0)7976 240171 (M) +44 (0)8454 336886 (x1001) (L) www.noakesltd.co.uk Noakes Limited, Registration #06920566 (England & Wales), 2 Berkeley Close, Northampton, NN1 5BJ

Re: [h323plus] error H.263

I think both the opal and h323plus community can benefit. http://www.h323plus.org/source/download/ffmpeg_x264.zip Place all files in your application directory. The FFMPEG (with w32threads) and X264 is built with mingw/msys. x264plugin_helper.exe is built with vs2008 and requires vs2008 runtime.

I have to admit to not being able to get the H.263 (or x264) codecs to compile and work under Windows, though I have only tried somewhat briefly. Unfortunately the authors of all the libraries mainly use Linux, though it is my understanding that it can be compiled using MinGW/Cygwin. I am sure the OPAL community would be incredibly grateful to anyone that can provide a pre-built binary for the H.263 (and x264!) codec. -------- Robert Jongbloed Vox Lucida Pty. Ltd.

OpenH323 version is 1.22.0 Compilation problems
by Jose P. Espinal 01 Feb '11

01 Feb '11

Hello List, I'm not sure this is the correct list to post this message, but searching on Google was not of much help. NOTE: Please feel free to point me to the correct place to search (in the case that this is not the correct list for this) I'm trying to install OpenH323 1.22.0 on Slackware Linux 13.0, I installed (without problems) ptlib-2.8.3 In the moment I run the ./configure script inside h323plus-1.22.0/ directory, it ends with the following error: ----- checking for /usr/include/ptlib/version.h... no Cannot find ptlib - please install or set PTLIBDIR and try again ----- I tried setting PTLIBDIR and PWLIBDIR, but had no luck. Is good to note that the system can see ptlib-config: ----- root@testbox_a:~# ptlib-config --version --libdir 2.8.3 /usr/lib ----- Also, I tried doing: touch /usr/include/ptlib/version.h , and after that, the configure script seems to go through without problem. Questions: a. What I'm missing here? b. What would be the possible consequences of creating an empty version.h, using 'touch'? (Will with break something?) PS. Sorry if any of this questions sounds obvious to you, I could not find any README or INSTALL doc inside sources packages. -- Jose P.

Everyone Just to let you know I may not be contactable over the next few days as the city where I live is under serious flooding. While we are above the flood level I may be uncontactable as the power or internet is intermittent. Simon

Re: [h323plus] Silk codec support

Robert I have checked the code into the h323plus CVS. There is no official ITU Generic identifier yet so it is using a Packetizer Identifer for the moment. You can contact me offlist to discuss.
