Change username@isp for the username your ISP knows you by. Often (but not always) it has an @isp bit at the end (It may be @dsl4.bt, for example). Also, change the vpi-number and vci-number for the VPI/VCI numbers for your country and ISP.
u VPI/VCI listi tamo u "tutoru" nema Srbije.... ostalo je sve namesteno,samo to "zeza"...
