Hi,
Thanks for your quick answer Simon!
In the h323ep.cxx file, I changed the value of H323EndPoint::initialBandwidth (in the class constructor) from 100000 to 10000000. Then I've been able to connect two clients at the same time!
I've been able to get the sound working with the PCMA codec. However, I get very weird results in the received video.
With "Force split screen video" unchecked, Computer B receives the Logo screen. When Computer C connects, it receives a green screen, while Computer B still receives the Logo screen, with a thin line showing the top of the Computer C webcam live input, on the top of the logo.
With "Force split screen video" checked, I usually get frozen artifacts on the two received videos (that are split). Nevertheless, I got once the first frozen video input from Computer C on Computer B only.
Note that H261 video codec has been used. May I miss something to fix the video support, like a lib/bin dependency for instance? Do you advise any client for testing, that would work better than Ekiga?
Finally, note that sometimes I still get the "Available bandwidth exceeded" log, making the openmcu server freeze.
Cheers, Jeremy Subtil Systems Engineer at Smile http://www.smile.fr/en/

Here is the offending line 2011/02/23 15:23:27.018 H225 Answer:be982700 Info H323 Available bandwidth exceeded
My Guess is that either ekiga is not setting correctly the bandwidth value in the OLC or the bandwidth setting of the MCU is too low.
Try increasing the bandwidth to 1000Mbps and try again. H323Endpoint::SetInitialBandwidth()

Hi there,
I compiled openmcu 2.2.5 on Computer A, along with ptlib 2.8.3 and h323plus 1.22. The server starts fine with all the expected codecs, and the output is the following:
