No authority found

This error is usually caused by a username/secret/type mismatch.

Valid Example Configs

Below is an example of working configs.

[server1]
type=friend
host=111.111.111.111
username=server2
secret=1234

[server2]
type=friend
host=222.222.222.222
username=server1
secret=1234

Basic Server Transactions

Below is basic call transaction from server1 to server2:

server1 connects to server2
server1 sends username: server2
server1 send secret: 1234
server2 looks for iax entry [username] e.g. [server2]
server2 checks secret
server2 accepts connection

This is outlined in more detail in Asterisk IAX authentication

Explanation

The 'No authority found' error is generated when an iax entry [example] matching the username sent can not be found.
It will also occur if the secret is wrong.
