Cisco Voice Gateway Configuration to Samsung Ubigate 1004 PRI Interface.

We are looking to move from direct ISDN30 connectivity on a BT PRI to BT SIP. To provision this to the Cisco Business Edition 6000 and 2900 voice gateway BT have provided the SIP service via a Samsung Ubigate 1004 unit. This unit is supposed to be SIP at the service provider end and then has 2 x PRI ports for connection to our voice gateway. 

That being the case we should be able to configure the PRI port on the voice gateway in the same way as it was previously. (assuming there are no stange non standard United Kingdom setting on the Ubigate device. 

This doesnt work though the PRI interface will not come up on the VGW router it doesnt even seem to get the layer 1 link level. Our pri config is as attached. I cant provide the BT/Samsung config as they wont provide it.
