A method of providing ring back in a telecommunications network (100) includes: receiving a call at a service switching point (114) for a called party (112) served by the service switching point (114), the call being from a calling party (122); encountering a trigger detection point (116) while engaging in a call setup for the call, the trigger detection point (116) being provisioned for the called party (112) at the service switching point (114); in response to encountering the trigger detection point (116), extending a first leg of the call to a service node (130) that provides ring back to the calling party (122); setting-up a second leg of the call between the service node (130) and the called party (112); bridging together the first and second legs of the call at the service switching point (114); and, removing the service node (130) from participation in the call after the first and second legs have been bridged together at the service switching point (114).
