Hi Simon, Several months ago I've seen that you've been working on H.460 support (H.460.18/H.460.19) in OPAL (OpenH323 v2): http://www.openh323.org/pipermail/openh323/Week-of-Mon-20060515/077132.html I can't find out if it is used in OPAL. Can you please tell me more or where can I get information on this? Thanks, Michael
