• establishing, on the basis of the received call party details, a communications session, separate from the telephone call, the communication session being established in response to the telephone call being established, wherein the communication session is for the communication of data to one or more of the at least two different user devices, from one or more of the at least two different user devices, or to and from one or more of the at least two difference user devices;
• generating, from an identifier specified at one of the at least two different user devices, a transmissible identifier identifying one or more downloadable resources, the transmissible identifier being operable to, in response to download of the one or more downloadable resources using the transmissible identifier, associate a predetermined identifier with the download;
• and
• enabling the download of the one or more downloadable resources to another of the at least two different user devices using the transmissible identifier.

• generate, from an identifier specified at the telephony user device, a transmissible identifier identifying one or more downloadable resources, the transmissible identifier being operable to, in response to download of the one or more downloadable resources using the transmissible identifier, associate a predetermined identifier with the download;
• and
• transmit the transmissible identifier via the communications session.
