Your comment is really constructive.
I did see some buggy devices that send fake IP/port on OLC.
Indeed in OnStartLogicalChannel, the remote IP/port is
retrieved from OLC instead of OLCAck. So that's a problem.

I'll re-consider the architecture.

I don't really understand what you mean.
But I can guess what you concern.
You are afraid Openh323 been changed in future
so that my implementation will be broken?
