Cool IPO V9.1 with XT500 MCU 9

I have a customer who has an IP Office with a small XT5000 Scopia MCU 9 everything works ok internally but he has another site which has an old tanberg system which is connected via an ISDN, If he calls from his scopia sytem via the DDI they can hear the number ringing but the tanberg doesn't respond whatsoever? any ideas what I am doing wrong?

the scopia unit is using ISDN to dial out and the tanberg is also on ISDN, the scopia has a static IP address for public facing network
