I tried to add custom VOIP provider from the GUI but after I selected custom voip the next screen opened asking for comment and host name etc… but when I tried to enter something the form did not allow me to enter anything.
Then I tried to edit user.conf files manually but then I found they were read only file and I was not allowed to edit them. I logged on as root and changed the file permissions but still I could not edit any of the file like users.conf sip.conf or any other .conf file in /etc/asterisk directory.
I was using admin account. Can some body help?
