Abstract

A system comprising: a first user device and at least a second user device for a same user, at least one of the first and second user devices being a household media appliance, and each being installed with a respective instance of a communication client application for conducting voice or video calls over a packet-based network. Each instance is associated with a same user identifier identifying the same user, a first of the instances is associated with a first subidentifier, and a second of the instances is associated with a second subidentifier. The instances are configured so as, during an ongoing call conducted over a first network connection established based on the user identifier and the first sub-identifier, after the call has been answered, to establish a second network connection based on the user identifier and the second sub-identifier and to switch the call to the second network connection.
