H4K V6 CFU ISDN BRI

Hi

I have a H4k V6. From V4 to V6 there is a CFU problem I am picking up.
A ISDN BRI device activates a feature, H4K rejects.

Does anyone know how an ISDN device transmits features to the H4K? I ran a trace and it does not pickup any unsuccessful activations or deactivations.

Is there an application that I can simulate e.g. ISDN supplementary service feature requests/response to another device? In that way I can troubleshoot the H4K.

Regards
Flame

It transmits on the signalling channel.
A trace should show up any signalling between them.
Failing that use an ISDN tester
