An Istec-1008 TK-Anlage/PBX cohabits the isdn line & drives my phones. The problem did not occur with bisdn (I think it used to with old bisdn, but then by bisdn-097 it had gone away). What the cause is I have no idea, but having 2 isdn systems I can afford to apply & test patches to one if someone want to send diffs to try. PS currently both hosts are Creatix 16 cards, both 486, both 2.2.5, one is i4b-51, one i4b-60, both going to 2.2.6+60 soonish. Julian Julian H.
