A customer has 30 DDI's, they want these DDI's to be displayed to the called party when going over the PSTN as opposed to just the main number being displayed. Teh problem is that no matter what DDI phone makes an offnet call only the main number is being displayed. We have CCM 6.1.
can anyone explain at what precise time the output of debug isdn Q931 is taken? is it at the exit point of the router's E1 interface after all translations etc, is this the command that can confirm that is the last calling number info before the telco receives it?
I can only assume that the carrier, in this case BT (UK) is just using the main number. Is this correct?
