The present invention enables the CCE to store intelligence about the services the subscribers use as companion data to the IP route to reach the desired user. The present invention introduces a service indicator to allow the CCE to distinguish whether a call requires advanced application processing. If no advanced application processing is needed, the CCE uses its companion data of IP route to setup a call without communicating with an application server. This would enable the CCE to direct calls to advance application servers only when subscribers required advanced application processing, thereby reducing the overall processing time required to setup a call to avoid the problem of signaling timers expiring unnecessarily.
