Titolo: 2610 PRI vs. 803 BRI

Ciao a tutti,
Ho un problema nel collegare un Cisco 2610 con scheda PRI ( IOS 11.3(10)T )
a dei Cisco 803 con interfaccia BRI ( IOS 12.0(4)T1 ).
Se l' 803 chiama il 2610 la connessione ISDN si attiva ma il ping non va (
con debug ip packet vedo degli encapsulation failed ): non appena si fanno
dei ping in direzione opposta ( dal 2610 all' 803 ), il traffico IP passa
correttamente in entrambe le direzioni ... 
Se invece la linea ISDN viene alzata dal 2610 verso l' 803, tutto funziona
correttamente.
Ho provato varie configurazioni ( con o senza CHAP, con o senza dialer ) ma
con scarsi successi.
Senza il dialer pool l' 803 funziona normalmente ... ma "tira sù" due
canali BRI per parlare con il 2610.
Devo fare del semplice routing IP statico con autenticazione CHAP ed
indirizzi IP statici sulle interfacce ISDN: la chiamata deve poter essere
originata sia dal 2610 che dall' 803.
Allego le configurazioni e ringrazio anticipatamente chi vorrà aiutarmi (

Prova ad inserire il comando "isdn send-alerting" solo sul 2610 sotto
l'interfaccia BRI.
Fammi sapere !!!!!
Ciao

 Fammi sapere !!!!!
Per il momento ho piallato entrambi i router e ricaricato tutto ( IOS +
configurazioni ).
Sembra funzionare bene ( IOS 12.04 e dialer map ip x.x.x.x. name ecc ) ....
GRAZIE COMUNQUE !
Ciao.
