[h323plus] Unable to connect more than one client

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:

#openmcu -cd

However, when I try to connect Computer C with Ekiga 3 as well, it fails and
openmcu gets a strange beahior: endless log messages even when all clients
are disconnected, unable to connect a single client again, unable to access
the web interface anymore. The only thing I can do is to kill the daemon.
Here is the log I get:

Note that I get the same behavior using other clients, like VidPhone for

Do you have any ideas how I can get openmcu working?
