Titolo: CISCO 830 e INCOMPATIBLE DESTINATION su connessione ISDN

Qualcuno sa dirmi perchè la connessione fallisce ?
L'errore principale sembra essere INCOMPATIBLE DESTINATION !
Grazie a tutti !

cisco systems
Grazie a tutti, ma ci dev'essere qualche altro problema. Provo a spiegarmi
meglio.
Schema:
    eth Roma         ---------------
   ISDN             ----------------            eth Milano
  -----------------| RTRoma      |--------------------------| RTMilano

                            ---------------                                 
      ----------------
(Attualmente li sto provando nella stessa stanza dove ho due linee ISDN (una
solo ricevente) con una numerazione ip di test.
La rete di Milano deve collegarsi on-demand a quella di Roma (eventualmente
viceversa) con protocollo tcp-ip.
Il router di Roma risponde correttamente alla chiamata di quello di Milano,
scrive di essersi connesso al numero chiamante, poi si disconnette dopo il
fallimento della connessione.
Se utilizzo il programma fast-setup, si blocca in fase di test subito dopo
che appare la scritta controllo user e password.
Credo sia un problema PPP, ma il debug PPP non mi sembra mostrare nulla di
rilevante, nel senso che mi sembra si blocchi prima (il debug che ho
mostrato era : isdn event, isdn q931, ppp negotiation e ppp chap.
(Se provo ad usare il programma config-maker la configurazione è la stessa,
ma in più mi aggiunge comandi broadcast che producono un impegno ciclico
della linea). La configurazione del router ricevente è la stessa di quello
chiamante con le dovute differenze, ma forse non so bene come si deve
configurare ppp che non l'ho mai fatto e a dire il vero è la seconda volta
che configuro un router ... siate buoni.
Configurazione di RTRoma (linea isdn ricevente):

Lo schema mi era venuto un pņ male spero che ora vada meglio, i router sono
803 non 830 !

Pare che una delle due borchie isdn che utilizzavo (quella solo ricezione)
sia solo ricezione perchè è una multilinea attaccata al centralino (pensavo
che rispondendo in voce fosse normale) immagino che il problema sia questo.
Se qualcuno me lo può confermare, grazie !
