I have the same concerns for G.729E.

<<File: FILE0001>> Tom,
section 3 of RFC1890 indeed specifies how additional payload types have to be registered with the IANA. Table 2 in section 7 specifies the assigned (and unassigned) payload types at the time of publication of the RFC (presumably). This table is no longer in line with the table that can be found at the IANA Web site (http://www.isi.edu/in-notes/iana/assignments/rtp-parameters), however.
Since G.729 is not present in either of these tables, it would seem that somebody will need to undertake the action to do so. Especially because H.225.0 _does_ specify a payload type for G.729 and I think it is desirable that the code that is being used is not assigned (inadvertently) to some other codec.
Whose responsibility would it be to do so? ITU-SG16?

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.
