I agree that I shouldn't be mucking with the dialog when I don't
understand the protocol properly :-)

Again I agree, that's why the original question was, how can I detect BYE. But
having been able to detect BYE, I have not been able to convert that
to a CANCEL.
Do you know how?

That's the strange part. I'm seeing the errors returned are 408 and 487 and
the Cseq is linking them to INVITE and not BYE. Or did I misinterprete Cseq?

Thanks for the help.
