Returns the value of the attribute with the given key.
This is particulary important when a response contains special attributes that are dependent on the action that has been sent.
An example of this is the response to the GetVarAction. It contains the value of the channel variable as an attribute stored under the key of the variable name.
Example:

                    GetVarAction action = new GetVarAction();
                    action.setChannel("SIP/1310-22c3");
                    action.setVariable("ALERT_INFO");
                    ManagerResponse response = connection.SendAction(action);
                    String alertInfo = response.getAttribute("ALERT_INFO");
                

As all attributes are internally stored in lower case the key is automatically converted to lower case before lookup.

public string GetAttribute(
	string key
)

Public Function GetAttribute ( 
	key As String
) As String

public:
