Titolo: problemi funzionamento linee ISDN con cisco as5200

Salve,
sto provando a configurare un allacciamento PRI ISDN con cisco as5200
ma quando gli telefono dall'output di debug vedo che
rileva la telefonata ma mi disconnette subito: non tenta nemmeno
una qualche forma di autenticazione.
La scheda ISDN e' una DIVA configurata in modo assolutamente standard
(switch-type DSS1)
NB: l'ISDN mi e' quasi completamente ignoto.
NB: ho cercato di seguire i manuali del cisco.
NB: l'ISDN troubleshooting guide del cisco dice che per il mio
     problema la soluzione potrebbe essere di modificare i valori
     dialer idle-timeout e dialer fast-idle
    Ho giocherrellato un po' con questi, ma non ho avuto successo.
Qualcuno puo' gentilmente aiutarmi?

Ciao,
  a quanto mi risulta lo switch-type del BRI e basic-net3 e non DSS1, prova
a cambiare questo parametro sulla DIVA.
Ciao.
Stefano Coluccini.

In teoria e' vero.
Il problema e' chi ha configurato la DIVA mi ha detto che non lo
supporta
Mi e' sembrato strano
Prima di sbattermi per cercare altre eventuali cause rivedro' la
configurazione della scheda
Grazie mille.
Saluti
