The FreeSWITCH core configuration is contained in autoload_configs/switch.conf.xml

Default key bindings

Function keys can be mapped to API commands using the following configuration:The default keybindings are;F1 = helpF2 = statusF3 = show channelsF4 = show callsF5 = sofia statusF6 = reloadxmlF7 = console loglevel 0F8 = console loglevel 7F9 = sofia status profile internalF10 = sofia profile internal siptrace onF11 = sofia profile internal siptrace offF12 = versionBeware that the option loglevel is actually setting the minimum hard_log_Level in the application. What this means is if you set this to something other than DEBUG no matter what log level you set the console to one you start up you will not be able to get any log messages below the level you set. Also be careful of mis-typing a log level, if the log level is not correct it will default to a hard_log_level of 0. This means that virtually no log messages will show up anywhere.
