GnuGk and Asterisk IVR

Hi,
I am working on a H.323 project which involves GnuGk and Asterisk My
current goal is to provide IVR functionality for the H.323 users which
register through GnuGk(eg. call credit information)
I have successfully built a H.323 platform using GnuGk - it uses SQL
accounting and authorisation. Now I am trying to integrate it with
Asterisk in order to provide IVR functionality as I already have working
Asterisk platform with all the needed components realised by AGI scripts.
To come to the point...I have added ASterisk as a permanent endpoint
gateway in GnuGk. What am I trying to accomplish is routing a prefix
"02" to Asterisk and receiving IVR messages from it. For the preliminary
tests I am just using the PLayback application but unfortunately I can't
get it working. Here are the components of the test setup. - GnuGk
v.2.2.3, PwLib v 1.9.0, OpenH323 v. 1.17.1, Asterisk
SVN-branch-1.2-r14140, OH323 channel driver for Asterisk:
asterisk-oh323-0.7.3.
I manage to route the calls to Asterisk but it can't fetch the H323ID of
the calling party and therefore the channel appears as unknown. Here are
the configuration files of my servers and the output of Asterisk CLI.
Asterisk CLI output:
*CLI> -- Registered with gatekeeper 'xxx (at) xxx.xxxx.com'.

As you can see GnuGk listens on port 1720 and Asterisk on 1730 as they
are on the same interface. I have tried Using the Dial application but I
think it is not appropriate as I am not trying to open a new outgoing
channel but just return a Playback message on the incoming one.
I was wondering whether what I am trying to achieve is possible and if
yes where are the mistakes in my configuration.
Any help or suggestions would be truly appreciated
Thanks in advance,
Angel Ivanov
