A system may include a call controller configured to receive a refer message configured to transfer a first endpoint of a call session, the call session being between at least the first endpoint at a first communications device and a second endpoint at a second communications device, the refer message indicating to transfer the first endpoint from the first communications device to a third communications device. The call control may be further configured to subscribe the first communications device to notification messages associated with the referral of the transferred call session, the subscription to the referral extending beyond the call transfer until termination of the call; and send, through the subscription to the first communications device, a notification message indicating termination of the transferred call.
