    O da işe yaracakdır ancak sanki sorun modemlerin buluşması ile ilgili olabilir. Sen debug yapmadan önce
     
    service timestamps debug datetime msec
    service timestamps log datetime msec
     
    yazarsan olayların tam olarak ne zaman gerçekleşiğini görürsün.
    Ayrıca aşağıdaki debugların sonucu daha fazla işine yarabilir.
     
    debug chat
    debug modem
    debug ppp neg
    debug ppp err
    debug ppp auth
    debug dialer
     
    Son olarakda routerda kullandığın modemi kendininki ile değiştirip denemen işe yarayabilir. Mesela aşağıdaki başarılı bir modem bağlantı logu

            dialer-group 1 satırını yazmışsınız fakat bunu bir access-list'e bağlamamışsınız.
            Yani access-list 1 de yazmanız gerekir.

            Mrb arkadaşlar

             

             usrobotics modemle yaptığım dial backupda serial0 down olduğunda serial1 line modem e bağlanıyor. Dialer stringi çeviriyor. Dialer stringi çevirdikten sonra bağlantı kuramıyor. ( kendi bilgisayarımdaki modemle bu username ve passwordle bağlanabiliyorum) neden kaynaklanabilir?

            Aldığım hata :
