[Tech] Dial-in ISDN

[Stefano]

Ho un computer con su un modem interno ISDN PCI Atlantis con Mandrake
9.1
Si connette ad internet senza problemi, ma non ne vuole sapere di fare
accettare connessioni di dial-in dall'esterno.
Gli Howto disponibili in rete sono quasi tutti in tedesco (cioe'
incomprensibili).
Qui sotto vi c'e' un po di log e la configurazione (i numeri di telefono
sono stati mascherati)
Come si vede bene dal log, l'interfaccia ISDN rileva ma ignora
completamente le chiamate in arrivo.
Dove ho sbagliato ?
