This invention provides methods and apparatus for providing customised prior-to-answer and in-call media playback telephony services. The services allow for playback of customised media content to calling parties in the form of customised ringback tones, engaged tones, call holding, call transfer tones and other content such as pre-recorded announcements. The media content for playback is stored in equipment associated with subscribers and playback of the media content is originated from the subscriber equipment. The invention allows subscribers to give their telephony services a personal touch as they can choose different items of media content for playback to different calling parties. As the media content is stored on subscriber equipment local to subscribers, no additional network resources such as data storage and data processing facilities are required. |
