How to change Asterisk manager password
This controls the asterisk 'manager' users that are allowed to connect to the asterisk manager interface.
You can have as many users in here as you'd like (for example, an operator panel might use one) and in fact, you should have different users for each application.
FreePBX requires a user that has a definition like the following:
[admin] secret = secret123password deny=0.0.0.0/0.0.0.0 permit=127.0.0.1/255.255.255.0 read = system,call,log,verbose,command,agent,user write = system,call,log,verbose,command,agent,user
There needs to be a corresponding entry in /etc/amportal.conf
