at the call control system, receiving, from the second communication client associated with the user, a communication session transfer request, the second communication client being located on a device associated with the user, the communication session transfer request having been generated by and transmitted from the device associated with the user; and
at the call control system, initiating transfer of the established communication session from the second communication client in the plurality of communication clients to at least the first communication client in the plurality of communication clients,
the notification being conducted on the basis of a preconfigured data set, specific to the user, identifying one or more of the plurality of communication clients associated with the user.
