+Gateway hierarchy
+========================
+
+Service		org.bluez
+Interface	org.bluez.HandsfreeGateway
+Object path	[variable prefix]/{hci0,hci1,...}/dev_XX_XX_XX_XX_XX_XX
+
+This interface is available for remote devices which can function in the Audio
+Gateway role of the HFP profiles.  It is intended to be used with external
+telephony stacks / handlers of the HFP protocol.
+
+Methods		void Connect()
+
+			Connect to the AG service on the remote device.
+
+		void Disconnect()
+
+			Disconnect from the AG service on the remote device
+
+		dict GetProperties()
+
+			Returns all properties for the interface. See the
+			properties section for available properties.
+
+		void RegisterAgent(object path)
+
+			The object path defines the path the of the agent
+			that will be called when a new Handsfree connection
+			is established.
+
+			If an application disconnects from the bus all of its
+			registered agents will be removed.
+
+		void UnregisterAgent(object path)
+
+			This unregisters the agent that has been previously
+			registered. The object path parameter must match the
+			same value that has been used on registration.
+
+			Possible Errors: org.bluez.Error.Failed
+					 org.bluez.Error.InvalidArguments
+
+
+Signals		PropertyChanged(string name, variant value)
+
+			This signal indicates a changed value of the given
+			property.
+
+Properties	string State [readonly]
+
+			Indicates the state of the connection.  Possible
+			values are:
+				"disconnected"
+				"connecting"
+				"connected"
+				"playing"
+
+HandsfreeAgent hierarchy
+===============
+
+Service         unique name
+Interface       org.bluez.HandsfreeAgent
+Object path     freely definable
+
+Methods		void NewConnection(filedescriptor fd)
+
+			This method gets called whenever a new handsfree
+			connection has been established.  The objectpath
+			contains the object path of the remote device.  This
+			method assumes that DBus daemon with file descriptor
+			passing capability is being used.
+
+			The agent should only return successfully once the
+			establishment of the service level connection (SLC)
+			has been completed.  In the case of Handsfree this
+			means that BRSF exchange has been performed and
+			necessary initialization has been done.
+
+			Possible Errors: org.bluez.Error.InvalidArguments
+					 org.bluez.Error.Failed
+
+		void Release()
+
+			This method gets called whenever the service daemon
+			unregisters the agent or whenever the Adapter where
+			the HandsfreeAgent registers itself is removed.
