asterisk users - Dec 2003 - How do I get caller's number in oh323 ?

We have an h.323 based IVR platform. When we make a call to it using an
h.323 phone, it can see the callers number (ANI), but when we make a call to
it via asterisk, the call goes through OK, but we don't get the number. How
can I make this work?

h323.conf
======[general]
port = 1720
bindaddr = 0.0.0.0
disallow=all
allow=alaw
dtmfmode=inband
[ivr]
type=h323
context=default

extensions.conf
==========exten => 602,1,Dial,h323/7002@ivr
exten => 602,2,HangUp
