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

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 number of the zap channel to switch to dnd on.
This property is mandatory.
