Get the name of this action, i.e. "Login".

Get/Set the digest alogrithm when using challenge/response.
The digest algorithm is used to create the key based on the challenge and the user's password.
Currently Asterisk supports only "MD5".

Get/Set the event mask.
Set to "on" if all events should be send, "off" if not events should be sent or a combination of "system", "call" and "log" (separated by ',') to specify what kind of events should be sent.

Get/Set the key.

You can use this as a simple authentication mechanism.
Rather than have to login with a username & password, you can specify a ProxyKey that must be passed from a client before requests are processed.
This is helpful in situations where you would like to authenticate and execute an action in a single step.

Get/Set the secret to use when using cleartext login.
The secret contains the user's password as configured in Asterisk's manager.conf.
The secret and key properties are mutually exclusive.

Specify a server to which to send your commands (x.x.x.x or hostname).
This should match the server name specified in your config file's "host" entry. If you do not specify a server, the proxy will pick the first one it finds -- fine in single-server configurations.

Get/Set the username as configured in asterik's manager.conf.
