A user has access to first and second telephony services. A call setup request directed to a first telephony party identifier associated with the first service is received from a caller and it is determined that the user is not available via the first service. A call setup request is transmitted to a telephony service destination associated with the second service to establish a telephony session between the caller and the destination. Media data transmitted during the session is caused to be captured using a media capture device intermediate the caller and the destination. The captured media data or media data derived therefrom is stored in a media data store so that the user can access the media data after the end of the session to determine what media data was transmitted during the session. The stored media data or media data derived therefrom is made accessible by the user.
