Tony, I run Asterisk in verbose mode all of the time. What changes did you make (command line arguments, config files, etc). I don't ever have the problems that you are describing. As far as extra ttys - screen is included by default. It is a much more flexible and memory efficient way to support multiple ttys. Are you familiar with it? -- Kristian Kielhofner |

I am VERY much against the idea of an "Asterisk console". It appears that option also enables the console, which is a bad idea. If you enable an "Asterisk console" security on the system becomes non-existant. Anyone can walk up to the box and have full access to Asterisk AND the shell (using !) as the user running Asterisk (usually root). Not good. Consoles are not platform specific but the ability for a virtual terminal is limited to systems with VGA video and a PS/2 mouse and keyboard. Many AstLinux systems only have a serial port. I have never had problems using multiple v's or "set verbose". If we solve this issue, screen will work quite well! -- Kristian Kielhofner |

 This is a feature of asterisk and every version of asterisk that I=
have tried does not fork.  If it does not fork, then the rest of the=
init.d scripts do not run.  Asterisk runs just fine on astlinux with=
this option.  You will not notice asterisk having a problem, you=
notice that the mini-http does not load, and the console does not clear so=
