The number to enter for My Phone Number depends on your particular setup:
ISDN Card Directly Connected to Phone Outlet

signed to your ISDN line.
ISDN Card Connected to a Private Branch Exchange

the Euro-ISDN (EDSS1) protocol for internal calls. These exchanges have an
internal S0 bus and use internal numbers for the equipment connected to them.
