An example method is described in which a controller initiates, with a control point, control point discovery for an endpoint managed by the control point. The controller, receives, from the control point, a message in response to the initiation of control point discovery. The message is an Internet Protocol Detail Record (IPDR) message or Simple Network Management Protocol (SNMP) message that includes registration information of the endpoint. Based on the registration information of the endpoint, the controller determines an association between the control point and the endpoint. This allows the controller to apply a controlling function on the control point when the endpoint accesses a service via the control point.
