asterisk users - Feb 2007 - Using ooh323 with Gatekeeper controlled dialling

All,

I've fixed my problem getting Asterisk ooh323 channel to stay registered
with my Cisco IOPS gatekeeper, now I need to get dialling working.

I have the following:

    [Asterisk with ooh323] ----h323---- [Cisco IOS GK] ----h323---- [Radio
system OpenH323]
        192.168.1.5                                192.168.1.6                  
192.168.1.7

the Asterisk box has numbers like 8102001, 8102002, etc.   and the radio system
has numbers like 8172001, 8172002 etc.

Both devices are registered with the Cisco H.323 gatekeeper as gateways.

I have a PC with "Ephony H323 soft phone" which is also registered to
the Gatekeeper (as a terminal) - from this I can call 810xxxx and 817xxxx
numbers, so my routing in the Cisco GK must be about right...

!
gatekeeper
 zone local THORCOM int.thorcom.com 192.168.1.6
 gw-type-prefix 817* gw ipaddr 192.168.1.7 1720
 gw-type-prefix 810* gw ipaddr 192.168.1.5 1720
 no shutdown
!


What is the correct form of Dial() to use in extensions.conf on the asterisk box
to place an ooh323 call via the Gatekeeper?  What do I need in the ooh323.conf? 
I've tried several/many combinations without any success and I'm finding
the (very) limited documentation in the ooh323.conf file confusing...

In extensions.conf I've tried things like:

 
a) using ooh3232/${EXTEN}/peer-name

    exten => _817XXXX,1,Dial(ooh323/${EXTEN}/cisco-gk)


 
b) using ooh323/${EXTEN}/H232-ID

    exten => _817XXXX,1,Dial(ooh323/${EXTEN}/H323-GK)


c) using ooh323/${EXTEN}/ip-address-of-gatekeeper

    exten => _817XXXX,1,Dial(ooh323/${EXTEN}/192.168.1.6)


Everything results in:

    -- Executing NoOp("IAX2/thorcom-1", ""route-tetra:
routing call to: 8172008 via H.323/GateKeeper from: 8202001"") in new
stack
    -- Executing Dial("IAX2/thorcom-1",
"ooh323/8172008@192.168.1.6") in new stack
    -- Called 8172008@192.168.1.6
  == Everyone is busy/congested at this time (1:0/0/1)
    -- Executing Hangup("IAX2/thorcom-1", "") in new stack

back at the asterisk box and the following in the Cisco Gatekeeper logs:

Yes, when I place a call from the Ephony softphone on the same Gatekeeper I get
progress and ringing, callset up etc:

What do I need to do in the Dial() command and/or the ooh323.conf to get
Asterisk to place a H.323 call via the Gatekeeper and on to the 817xxxx gateway?
i.e. work like the soft-phone does?
