This is a template for anyone who wants to dial into an ISP with a cisco
router - this assumes that you have a static IP address...

'debug chat', 'debug confmodem' and 'debug ppp negotiation' (and
others) are your friend...

! these scripts are very specific to your modem and the login
! sequence and the response that you ISP's NAS requires mine are here
! as examples only...
chat-script dial-out "" "AT&F1" "OK" "ATDT\T" TIMEOUT 45 CONNECT
chat-script login ABORT invalid TIMEOUT 15 ogin: <login> word: <password>

! this corresponds to the line number that your modem is connected to
! usually 'line aux 0' do a 'show line' to see what line 'aux 0' is
! represented by (NOTE: I'm not using 'line aux 0' in my example)
interface Async8
 ! point this to what ever interface the static ip address provided
 ! by your ISP resides on
 ip unnumbered Ethernet0
 encapsulation ppp
 no ip route-cache
 no ip mroute-cache
 load-interval 30
 dialer in-band
 dialer pool-member 1
 async default routing
 async dynamic address
 async dynamic routing
 async mode dedicated
 no peer default ip address
 no cdp enable

interface Dialer1
 ! point this to what ever interface the static ip address provided
 ! by your ISP resides on
 ip unnumbered Ethernet0
 ip access-group incoming in
 encapsulation ppp
 no ip route-cache
 no ip mroute-cache
 load-interval 30
 dialer pool 1
 dialer idle-timeout 86400
 ! in the 'dialer string' specify the number you are calling as the first
 ! argument
 dialer string 5551212 modem-script dial-out system-script login
 dialer-group 1
 ! set a peer default ip adress to the gateway address of the NAS you are
 ! connecting to
 peer default ip address 10.1.1.1
 no cdp enable

! set an ip route to the gateway address of the NAS you are connecting to
ip route 0.0.0.0 0.0.0.0 10.1.1.1
ip route 10.1.1.1 255.255.255.255 Dialer1

! line number that modem is attatched to 'line aux 0' in most cases
line 8
 exec-timeout 0 0
 modem InOut
 ! this is dependant on modem type you can autoconfigure your modem
 ! with 'modem autoconfigure discovery'
 ! you can do a 'show modemcap' for other types if you are not using a
 ! usr courier
 modem autoconfigure type usr_courier
 transport input all
 stopbits 1
 ! if you are using 'line aux 0' this can be no higher that 38400
 speed 115200
 flowcontrol hardware
