Titolo: Problemi con ISDN PRI su 3640

Sto tentando di far comunicare un 3640 ed un 1603 via ISDN.
Sul 3640 ho attestato un primario "dimezzato" (15 canali) , sul 1603 una
semplice BRI
Il 1603 comunica già con altri router in ISDN  , il PRI sul 3640 è stato
invece appena installato. Il problema è che dal 1603 riesco a comunicare
tranquillamente con il 3640 , la linea sale , vengo autenticato (CHAP) ,
pingo etc. etc.
Dal 3640 invece vedo che la linea sale ma non arrivo nemmeno alla fase di
autentica , dopo poco il tentativo di connessione va in timeout e linea
cade.
Si noti che non ci sono access-list di mezzo e che la stessa cosa accade
anche tra il 3640 ed altri router (761 ad es.) normalmente in produzione.
Ho debuggato quanto accade sia sul 3640 , sia sul 1603. Riporto i risultati
qui sotto.
Qualcuno ci capisce qualcosa ???
Ringrazio anticipatamente.

Prova ad inserire il comando " isdn send-alerting" sotto l'interfaccia fisica
PRI sul 3640.
Fammi sapere. Ciao
