Michal, I know that NetMeeting has the ability to use certificates for privacy and authentication, but all of the documentation I have seen seems to imply that it still uses T.120 to do the certificate verification. Given that NetMeeting was written before H.235 was created, this makes sense, but I have not actually verified this is the case. Do you have any information on this?
