troubleshooting

if asterisk doesn't start when running fwconsole start: 

Unable to connect to Asterisk. Did it start?

make sure the user and password for AMI access are correct: 

fwconsole setting --list |grep MGR

if result if like the following: 

| AMPMGRPASS | amp111 | amp111 
| AMPMGRUSER | admin  | admin

you should have the following on /etc/asterisk/manager.conf: 

[admin]
secret = amp111
