I added this support to chan_ooh323 last fall, and was included in
the asterisk-addons-1.2.2 release.  I wasn't able to fully understand
the Asterisk representation of channel states, so I did not add
MoH support.  What does work is transfer/hold retrieve from a H.323
endpoint.  I did not need support for Asterisk initiated T/H/R, so
that code may be incomplete (read completely untested on my part)
