paul, I have been looking for some clarifications on H.225-Annex G and somehow my mails to the editor, Michael Fortinsky from vocalTech are not getting answered. Since you are the editor for H.323, I was just wondering if you have any idea about who to contact now for any queries relating to H.225-Annex G in such a situation. Is there anyone else out there that is responsible for H.225- Annex G ? Thanks Archana
