Hi
I have done the following in class derived from H323EndPoint
this->AddAllCapabilities(0, 0, "*");
this->AddAllExtendedVideoCapabilities(0,P_MAX_INDEX);
Then during call I called
H323Connection::OpenExtendedVideoSession( unsigned role,H323ChannelNumber &) 
in H323EndPoin::OnConnectionEstablished()
In OpenExtendedVideoSession()
it breaks without opening extended video channel 
because the check 
(remoteCapability != NULL) fails.
I am trying to connect my application with Polycom PVX with H239 content enabled 
I couldn't find H239 sample on CVS on sourceforge.
Please help.
