User B connects a router with FXS port and accesses Internet through WAN port of 
that router. When B calls A, the voice signal will be sent to a remote router (C) through 
Internet. Then, the voice signal will be passed to switchboard (via S0 intern) and 
transferred to A through ISDN line (leaving Internet). Such route is named ISDN 
Off-Net
 (see blue route).
