Appendix VI Description of a typical H.323 system over IP This Appendix describes a typical H.323 stack. Figure VI.1 shows how RAS, H.225.0 call signalling and media are implemented using the IP infrastructure. The arrow between H.245 and H.225.0 points out that H.245 can be tunnelled in H.225.0. The arrow between H.225.0 call signalling and H.225.0 RAS points out that H.225.0 call signalling can be tunnelled in H.225.0 RAS.
