KBX & Asterix
Asterisk is currently configured with a management password of simply "gigatux" and this is set in /etc/asterisk/manager.conf
Elastix's configuration in /etc/amportal.conf had this set as awilo1. I have now changed this to 'gigatux'.
If you want to change this, make sure you change both files and that they match up.
Initial setup
If the user doesn't know, or cannot find, the default PBX password, this can be bodged by installing sqlite3 and manually changing the database file at /var/www/fusionpbx/secure/fusionpbx.db using the code from http://wiki.fusionpbx.com/index.php?title=Password_Recovery to create the right hashed password.
