+Methods void RegisterAgent(object path, dict properties)
+
+ Register a TelephonyAgent to sender, the sender can
+ register as many agents as it likes.
+
+ Note: If the sender disconnects its agents are

+
+ possible properties:
+
+ string UUID:

+ UUID of the profile which the agent is
+ for.
+
+ uint16 Version:
+
+ Version of the profile which the agent
+ implements.
+
+ byte Features:
+
+ Agent supported features as defined in
+ profile spec e.g. HFP.
+
+ Possible Errors: org.bluez.Error.InvalidArguments

+ void UnregisterAgent(object path)

+========================
+
+Service unique name
+Interface org.bluez.TelephonyAgent
+Object path freely definable
+
+ethods void NewConnection(filedescriptor fd, dict properties)
+
+ This method gets called whenever a new connection
+ has been established. 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.
+
+ If Endpoint is set the agent is responsible to
+ create an object implementing org.bluez.MediaTransport
+ and notify the Endpoint using org.bluez.MediaEndpoint.
+
+ possible properties:
+
+ strict Device:
+
+ BlueZ remote device object.
+
+ string UUID:
+
+ Profile UUID of the connection.
+
+ uint16 Version:
+
+ Remote profile version.
+
+ byte Features:
+
+ Remote profile features.
+
+ string Endpoint:
+
+ Optional. Endpoint bus id.
+
+ string EndpointPath:
+
+ Optional. Endpoint object path.
+
+ 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 TelephonyAgent registers itself is removed.
