What do you mean? DID is just mapping of an external number to an internal number. So when you have a range of numbers, just map them to internal DN's

Hi,

ISDN links (E1, T1 or PRI) are always DID. I am not aware that you configure them using two step dialing similar to FXO or E&M. You won't see this in debugs are this is natively the case.
