The present invention relates to a method and system for re-routing a call which has been routed from a calling party (1) through a communication network to a destination (4). A need to relay the call to another destination (5) is identified and a subscriber identification of the calling party (1) is signaled from the other destination back to the communication network using a call drop-back function. Preferably, the subscriber information is then used to derive a routing information of the other destination (5) which may be a right destination in case the initial destination (4) was a wrong destination. Thus, a call drop-back feature is used to route calls even in cases where a subscriber is connected to a wrong destination. Thereby, an effective re-routing can be provided in cases where a subscriber identification is not provided in the call, such that a single service access short code can be used by all subscribers irrespective of their mobile terminal and their location.
