I am not getting GUI after installing ASteriskNOW.
I have installed AsteriskNOW 5.211(32bit).After installation login prompt appears without any error. I am able to ping the ipaddress from another computer ,but I am not getting GUI in web browser. Also when i type asterisk -vvvvr to enter to cli it is showing command not found. Please help to solve it
