I can add that it works perfectly from a SIP phone to H.323, but not
from ISDN to H.323. (and it works from ISDN to SIP phone).

My symptom is the same: you can hear H.323 from ISDN, but not hear
ISDN from H.323.

However I use H.323 from asterisk's recent CVS, not oh323. I use
codec GSM in h323.conf.
