+ * When we are going to offer CC to a caller, a lightweight
+ * container of structures is used. Once the caller requests
+ * CC, and the core creates the appropriate monitor structures,
+ * then the core_pending_cc_offer can be destroyed.
+ *
+ * These structs are stored in an ao2_container which is hashed
+ * based on the core_id of each element for easy lookup.

+	 * is an identifier for the instance of the core for which
+	 * this offer belongs. So even after the offer matures into
+	 * an official request for CC, the same core_id will be used
+	 * when making state machine transactions and the like.

+	 * device name of the calling channel. However, this may need
+	 * to be modified to include CID information or something to
+	 * more uniquely identify the caller. For instance, if an
+	 * inbound call over a trunk may be from one of several users,
+	 * so using just the device name as an identifier is not good
