+// VoipFeatureAccessCodes (class ID #147)
+//	The VoIP feature access codes ME defines administrable feature access codes for the VoIP
+//	subscriber. It is optional for ONUs that support VoIP services. If a non-OMCI interface is used
+//	to manage VoIP signalling, this ME is unnecessary.
+//
+//	Instances of this ME are created and deleted by the OLT. A VoIP feature access codes instance is
+//	needed for each unique set of feature access code attributes.
+//
+//	Relationships
+//		An instance of this ME may be associated with one or more SIP user data MEs.
+//
+//	Attributes
+//		Managed Entity Id
+//			Managed entity ID: This attribute uniquely identifies each instance of this ME. (R) (mandatory)
+//			(2-bytes)
+//
+//		Cancel Call Waiting
+//			Cancel call waiting:	(R,-W) (optional) (5-bytes)
+//
+//		Call Hold
+//			Call hold:		(R,-W) (optional) (5-bytes)
