ISDN to trixbox to Microsoft OCS (I just need to route calls between trunks)(Fixed)

I have been looking through the forums for a few days and haven't managed to find the answer so.........

We have a trixbox 2.6.2.3 setup connected to a PRI ISDN (E1) which works fine. Extenstions, softphones etc work.
We have a MS OCS 2007 R2 Mediation Server connected to it via a tcp sip trunk, OCS can make out going calls via the trixbox and ISDN OK.

Hopefully I am missing something obvious here (brand new to this) the issue is that I can't work out how to get the trixbox to route all incoming calls from the ISDN (we have 30 DDIs) to the OCS system.
Basically we are looking at using the trixbox as a simple ISDN---SIP gateway.

OCS ----> ISDN works
ISDN -----> OCS doesn't

Any suggestions, pointers appreciated.

(edit to clarify - ISDN calls to extensions on the trixbox work perfectly - it is just a question of how do I get the trixbox to pass everything incoming directly to the sip trunk and thus the OCS)

(Edit thinking that I may need to set up custom extensions but not sure what I need to do)
(Setup custom extension with sip/ocs/xxxx (xxxx is the extension number) in the dial field under custom technology).

Watching a call from Asterisk...... (real phone numbers have been replaced with xxxx)
Call originated from an extension local to the trixbox to an extesion on the OCS.
