Park,

MessageChannel, SIPRequest and others are all implementation classes which 
are not part of the JAIN API. It is not recommended / supported / portable 
to base your implementation on these

You are probably better of using the transport in the topmost Via header, 
i.e.

boolean isSecure( Message m ) {
  ViaHeader via = (ViaHeader) m.getHeader( ViaHeader.NAME );
  if (via!=null) {
    return ListeningPoint.TLS.equalsIgnoreCase( via.getTransport() );
  }
  return false;
}

Regards,
Jeroen
