There is no network interface associated with a call itself, but once you start speaking PPP on top, you get a ippp interface. > If you want a call on each B-channel of an > ISDN BRI, does that mean you should have two devices, e.g. i4bipr0 and > i4bipr1?

This interface are going to be clonabel soon (it's realy a bug that they are not yet) > Or does it represent more of a > physical ISDN connection between two endpoints? No, it's just a carrier for network configuration. You do not need to use them at all (like userland ppp does). > How is the PRI support in i4b? AFAIK it's functional, at least with the iavc driver.
