OPAL community! Every so often (usually annually) there is a large interoperability event run by the International Multimedia Telecommunications Consortium, see http://www.imtc.org/event/imtc-superop-april-2013-2 for more details, where all major, and many minor, manufacturers get together to try their gear out with each other and work out the misinterpretations of the specifications. I would really like to bring OPAL along to this event and test it out with as many other systems as I can. It should be obvious to everyone that this would be hugely beneficial to all user of the stack. Interoperability is the thing that causes the most pain out there. However, it is simply too expensive for me to fund by myself. The consulting work I do is not that lucrative! With air fares, hotel, IMTC fees etc, it would cost me about US$5,000, not including my time, which I would gladly donate to the community. I asked this question a few years back (2010) and got a resounding silence! (Apologies to the one non-commercial user that did offer something) So, let us see if we can do better this time. It is the same deal as last time, if enough of you out there commit some amount, be it $100 or $1000, and I can get close to the $5,000, then I go! I don't want any money until I think we are going to make it, then I will come knocking for the cash. /Please/, lend the OPAL community your support, especially the commercial users that have (hopefully!) made money out of OPAL. Consider how much you have saved in licensing fees! It should be a small investment to improve the quality of the software you sell. -- *Robert Jongbloed* /OPAL/OpenH323/PTLib Architect and Co-founder./ Commercial support at http://www.voxlucida.com.au |

This effort has been much more successful than last time, we are almost there! I have had confirmed promises of $4,350, including $3,000 from one company that wishes to remain anonymous. Some people understand that interoperability is /important/! We really should get to this event. It might only be $650 left, but really, I /do/ need to cover expenses. I am donating 5 days of my time, not including travel, for which I would normally charge US$5,250. I do not think it fair that I should pay any more than this. So, come on, a couple more smaller donations and we are there! I know you are out there ... *Robert Jongbloed* /OPAL/OpenH323/PTLib Architect and Co-founder./ Commercial support at http://www.voxlucida.com.au On 21/01/2013 11:38 AM, Robert Jongbloed wrote: > OPAL community! > > Every so often (usually annually) there is a large interoperability > event run by the International Multimedia Telecommunications > Consortium, see http://www.imtc.org/event/imtc-superop-april-2013-2 > for more details, where all major, and many minor, manufacturers get > together to try their gear out with each other and work out the > misinterpretations of the specifications. > > I would really like to bring OPAL along to this event and test it out > with as many other systems as I can.

I am very glad to report due to the very generous response from the community, I have made my target and will be going to the IMTC SuperOp <http://www.imtc.org/event/imtc-superop-april-2013-2>! I would like to thank everyone in the community for their support in making OPAL the quality product I believe it is. Working in Open Source can sometimes be a thankless and frustrating task, but every now and then faith can be restored in the power of the model. Some people really do "get it". Again, thank you all, and especially thanks to those that coughed up the cash. *Robert Jongbloed* /OPAL/OpenH323/PTLib Architect and Co-founder./ Commercial support at http://www.voxlucida.com.au On 31/01/2013 9:19 AM, Robert Jongbloed wrote: > This effort has been much more successful than last time, we are > almost there!

OPAL community, I have now returned from what I think was a successful attendance of the IMTC SuperOp! The "rules of engagement" of such an event prevent me from divulging too much detail on who could, or could not, do what with which product. This can be commercially sensitive, so is required to be kept within the walls of the venue. The big theme of the event was security. Everyone had TLS/SRTP capability, and wanted to test it. I tested OPAL with around a dozen vendors and failed on only one. I am willing to bet that that was their problem. And it was not any of the "big" names either, so of perhaps lower importance. A lot of testing of H.264 was done at various resolutions and bit rates. We were successfully interoperating at HD720 resolution in both directions. I did not test "high" profile, only "baseline", nor was HD1080 resolution. The only issue in this areas was that the Windows FFMPEG decoder we are using produced artefacts for some vendors. When run on Mac OS-X the problems disappeared. I am guessing this is because the DLL we use to decode is now quite old and needs an update. Note there were no issues with transmitted video. A piece of useful information from other attendees there, was a pointer to http://www.libav.org, which is fork of FFMPEG and looks to much more library/portability oriented. These guys do nightly builds for Windows in both 32bit and 64bit variants. Hopefully, all the numerous compile issues we have had will go away at last if we just require this library. Some work yet to done there. Wideband audio was also popular, we tested G.722-64K and G.722.1-32K extensively. There was an issue with G.722.1, where we were not sending big-endian words over the wire. This was fixed on site. Audio is, however, very boring to most vendors. It's well established these days. Secondary video channel, a.k.a "presentation video" or "content role video" or H.239 video, was tested with several vendors. For both H.323 and SIP, if it was offered to us, we accepted and displayed the second video stream correctly. However, we were unable open a /transmit/ secondary video. For SIP this was because we do not yet support BFCP (Binary Floor Control Protocol) so cannot obtain the "chair" allowing us to send. For H.323/H.239 a quick hack was tried to get the chair (or token in H.329 language) and this was partially successful. The one MCU I had time to try would now allow the transmission of the video, however, it did not display it. Wireshark logs showed all was being sent correctly. Unfortunately, the vendor and I could not determine why before we had to move on to the next test. Some testing of signalling features, hold/resume, transfer etc was done, but this was not a high priority and generally worked. The notable exception was one "big name" MCU that did not understand how to do "call forwarding", in SIP that's where you send 302 response to tell the caller to go somewhere else. An alternative is to send a REFER, which I tried, also without success. I got a shrug of the shoulders when I said it was not very useful to have to answer the call before forwarding to another endpoint. Not much we can do if the other guy does not support the standard! The observant of you may have noticed a number of check ins over the last week. Nearly all of the various issues that were encountered were fixed on the spot and retested. A number of changes were done, primarily to OpenPhone, just so I could easily test features. The result is the only major open item is moving to libav support, which I will try and do over the next week or two. I would like to again thank the sponsors of my trip, I hope they too think that it has been a worthwhile exercise. Maybe we can do this again net year! *Robert Jongbloed* /OPAL/OpenH323/PTLib Architect and Co-founder./ Commercial support at http://www.voxlucida.com.au On 14/02/2013 11:47 AM, Robert Jongbloed wrote: > I am very glad to report due to the very generous response from the > community, I have made my target and will be going to the IMTC SuperOp > <http://www.imtc.org/event/imtc-superop-april-2013-2>! > > I would like to thank everyone in the community for their support in > making OPAL the quality product I believe it is.
