This method at first comprises the step of a call session control network element intercepting the incoming IP multimedia call. Subsequently, the call session control Network element upon intercepting of the incoming IP multimedia call activates a dedicated primary application server. The primary application server, upon analysis of the incoming IP multimedia call presents the incoming IP multimedia call to the called party terminal together with a set of service applications for answering said incoming call.
