hi All, its probably very simple but i can't find the way to it. i have some b410p cards and use them to connect to ISDN2, this works OK for calling but i need to have 1 line to be send to the fax machine. the fax machine is a modem connected on another machine with hylafax. as far as i can figure out i need to set 1 of the slots, the one leading to the fax, in the b410p in NT mode by
