As I understand it (and I'd better be right, because I have to do similar things for H.248!) the stuff initially defined in the RFC that sets up the registration process (RFC 1890) does not go into the IANA database -- only subsequent registrations.

H.225.0 specifies that the payload types for G.723.1 and G.729 are 4 and 18 respectively. When I take a look at the registered payload types at the IANA, these two codecs are not listed.

Does this mean that the IANA list is not up-to-date or that these codecs are not officially registered.
