Abstract
A communications device () maintains profile data including a device identity and a calling line identity (CLI) associated with a PSTN connection () both on the device itself and also on an authentication platform (), in order that the device can access a service () which requires knowledge of the CLI by way of a packet-switched connection (). In the event that the CLI data in the communications device is corrupted or lost, the communications device transmits a request for re-authentication to a reactivation server () together with the device identity. On receipt of the request, the reactivation server retrieves the stored profile () from the authentication platform (), and returns it to the communications device () to allow the profile to be restored. This process can be done without the user needing to send a new request for service over the PSTN link ().
