sx20 with ISDN Link Unable to call VMR

We are using a SX-20 running TC6.2.1 and a ISDN Link IL1.1:

We are using 3xBRI connections to connect to a MCU(VMR).

1..If we call the MCU using our MXP6000 on the same lines we can connect no problem.

2..If we call from SX-20 though the ISDN Link we connect with no Video or audio and after 32 seconds it disconnects

3..We can call from an SX-20 with isdn link over Isdn to another Sx-20 with Isdn link no problem.

Any Help With this a Have raised a TAC but its been weeks and it just goes around in circles.

The unit we are tring to connect to is a Polycom RMX2000 in MPMx card configuration running the latest GA software from Polycom being RMX8.1.

we have tried two differant providers and have the same problem but only when we use an ISDN link....

called from differant locations so i dont think its the lines

Left some logs here from us trying to make a call
