Method and arrangement for making a call-setup
Abstract:
A method and arrangement for providing a ring-back presentation to a calling terminal after receiving a call setup request from the calling terminal (A) for a first communication session (308) with a called terminal (B). A second packet-based communication session (310) is established with the calling terminal, independent of the first session, and pre-defined media content is provided as said ring-back presentation (312) to the calling terminal over the second session. Thereby, ring-back presentations to waiting callers can be selected from a great range of media types, including visual media. A calling user can also control the playout or display of the ring-back presentation irrespective of when the call is answered.
