ISDN outband call not working or not permitted?

Hi guys

I got a 2 devices CPE_BE and DC_UK. From CPE_BE I cannot perform any ISDN outband call (international and national) however from the DC_UK I can call the ISDN line of CPE_BE, I can see the authentication etc etc, call is setup properly.

I think it could be the telco supplier not permitting the outband call on their ISDN line.. I am not sure it can be a network issue else if the inbound call shouldn't work?

Log from CPE_BE when I tried to call DC_UK:

nop it's not here anymore

Please set "dialer wait-for-carrier-time" to something like 30, explicitely.

Even with the command setup at 30 instead of 4 I still have the 4 seconds disconnection

I know it's crazy, I start to become nuts :'(
