ISDN BRI dialout help

[Zafar]

Hello,   I am trying to configure ISDN BRI for dialout using 2503 but could not connect to remote access server of the ISP. I have taken a ISDN dialup account from ISP and it has given me "userid", passwd and dialup number. I tried these through normal dialup (windows dun) and it connects succesfully. Now I have following configuration for my 2503 router but this could not connect. Please advise if I am missing something as I am new to ISDN and doing it for the first time     ! interface BRI0  ip address negotiated  ip directed-broadcast  encapsulation ppp  no ip split-horizon  dialer idle-timeout 2147483  dialer string 12144444  dialer hold-queue 10  dialer-group 1  isdn switch-type basic-net3  ppp authentication pap  ppp pap sent-username <myusername> password <mypassword>   ! ip route 204.71.200.45 255.255.255.255 BRI0   ! dialer-list 1 protocol ip permit     when I ping 204.71.200.45 , following appears on the terminal:     Type escape sequence to abort.
