select appropriate BRI switch type. Selected BRI switch type must match the one congured on ISDN device.
Once that is done, you will always need to set the phone numbers (i.e., DN) and, if the congured switch type
requires it, the SPID numbers.
“Caller ID”, or, in formal ISDN terminology, “calling number identication presentation”, is always enabled and a
part of standard call setup procedure dened in Q.931 standard.
