Hello everyone,

I want to make a ISDN dialback connection with my Cisco 803.
I use a windows 2000 workstation as dialback client, so the win2000 hosts
dials to the cisco803,
the cisco 803 then does a dialback to the win2000 host.

Unfortunatly, this doesn't work as I would suspect.
This was my initial (relevant) config, this is without dialback.

<>
username test password 7 xxxxxx

interface Ethernet0
description connected to InternalLAN
ip address 192.168.1.252 255.255.254.0
!
interface BRI0
no ip address
encapsulation ppp
dialer pool-member 1
isdn switch-type basic-net3
ppp callback accept
ppp authentication chap
ppp multilink
!
interface Dialer1
description connected to dialback
ip unnumbered Ethernet0
encapsulation ppp
no ip split-horizon
ip tcp header-compression passive
no ip mroute-cache
dialer pool 1
dialer remote-name test
dialer-group 1
peer default ip address dhcp
no cdp enable
ppp authentication chap pap

</>

This works fine, the next step was to add the dialback option.
unfortunatly this doesn't work...
the new (dialback) config is this one:

<>
username test password 7 xxxxxx

interface Ethernet0
description connected to InternalLAN
ip address 192.168.1.252 255.255.254.0
!
interface BRI0
no ip address
encapsulation ppp
dialer pool-member 1
isdn switch-type basic-net3
ppp callback accept
ppp authentication chap
ppp multilink
!
interface Dialer1
description connected to dialback
ip unnumbered Ethernet0
encapsulation ppp
no ip split-horizon
ip tcp header-compression passive
no ip mroute-cache
dialer pool 1
dialer remote-name test
dialer string 0123456789
dialer caller 0123456789 callback
dialer-group 1
peer default ip address dhcp
no cdp enable
ppp authentication chap pap
</>


I added the 2 commands (for dialer1):
dialer string 0123456789
dialer caller 0123456789 callback
the telephone number 0123456789 is the number of the win2000 isdn line.


should I add any aditional config?
does anyone know how i should configure the win2000 client?
I played around with the callback option in the advaced > dialup preferences
menu in "network and dial-up connections",
but it didn't seem te make diference.

at the end of the message you'll find some debug info:


any advise?

thanks in advance,
Andree
