OpalH224Handler * PhEndPoint::CreateH224ProtocolHandler(H323Connection & connection, unsigned sessionID) const
{
return new CVcsChannelh224(connection, sessionID);
}

CVcsChannelh224 is my class derived from OpalH224Handler
and
PhEndPoint derived from H323EndPoint

but still my application crashes at h224Handler->StartTransmit(); in BOOL H323_H224Channel::Start()
I have tested it using polycom and mirial.

But when I use my application at other end. the cnannel get released by calling
if (chan != NULL) {
chan->CleanUpOnTermination();
delete chan;

I think I am not able to add capabilities right by adding :
H323_H224Capability *p = new H323_H224Capability();
capabilities.Add(p);

Is there something that I am missing.
and one more thing Can I use PTRACE in Windows.

Sorry for the delay in replying.

I hadn't fully tested the implementation.

I think you have not loaded your derived h224 handler through the H323EndPoint function override I specified in the last email

hi Simon
As you suggested I have added H323_H224Capability(). The brief code is

H323_H224Capability *p = new H323_H224Capability();
capabilities.Add(p);
in a class derived from H323EndPoint.

The watch window here doesnot show much.

But exe crashes in BOOL H323_H224Channel::Start()
at
h224Handler->StartTransmit();
I think it is not getting pointer right

Can you guide me from there.

alam.
