oi have an old rapid server used as a router that has a number of dialin lines. Both pstn getty and isdn using hisax drivers used to work fine with either xp or linux. now i tried a computer with vista and now it works only on analog. Using isdn no longer works. It gives an error after lcp negotiation at ppp phase the same pc same Ta, same settings booting xp works. does someone of you have some ideas?
