Titolo: Cisco 2620 NM-AM e callback RAS NT

Buongiorno a tutta la lista,
Dovrei configurare un 2620 con un modulo nm-am 
(8 modem analogici) perche' si colleghi ad
un RAS NT e richieda il call-Back e lo autentichi.
In parole povere un client sulla rete del router fa alzare
la chiamata, il router si autentica sul RAS NT e richiede
il callback, il RAS chiama e si autentica al router.
Ho cercato molto ma tutte le configurazioni si basano sul
callback al contrario, cioč di solito č il router che esegue
il callback verso il client e non viceversa.
Mi rendo conto che questo possa sembrare molto contorto ma 
il fatto č che il "lato" RAS deve pagare la chiamata ma č il 
lato router che deve dare inizio al processo di creazione del
link.
Grazie a tutti per l'attenzione e per gli eventuali esempi di 
configurazione.

Il tuo obiettivo sembra essere quello di configurare un router come
"callback client", segui questo link, dovrebbe fare al caso tuo.

Hope this helps

 "callback client", segui questo link, dovrebbe fare al caso tuo.
Il mio problema è che riesco a collegarmi al ras nt se non richiedo
callback.
Se richiedo il callback il server Cisco riceve il reset della
connessione ma non
riceve callback dalla macchina NT che è configurata per eseguirlo ad
un numero fisso.
Segue la configurazione....

Scusate la lunghezza del post ma la domanda alla fine è molto semplice
come faccio a forzare il ras a richiamare il cisco? e come faccio a
passare dinamicamente al ras il numero da richiamare su linea
analogica senza caller id?
Grazie a tutti per l'attenzione
