I didn’t know anyone still used ISDN!

I sure a lot of people still do, why change, especially smaller companies that have no desire to change circuits and phones.

Probably no one is using Basic Rate Interface (BRI) circuits, they are using Primary Rate Interface (PRI) ISDN circuits, I supported and installed hundreds both of them at a Cisco TAC and for a couple of major companies.
