The invention relates to a method for controlling a call attempt by employing an intelligent network. The method comprises the steps of (a) processing the call attempt according to the originating half BCSM (O_BCSM) at a first point (SSP_A) having a service switching function (SSF), (b) resuming the processing of the call attempt according to the terminating half BCSM (T_BCSM) at a second point (SSP_B) with a service switching function (SSF), and (c) providing a service request from the processing that employs T_BCSM to a point (SCP) having a service control function (SCF). In order to be able to offer versatile IN services to the called subscriber as well, the processing of the call attempt is returned to the point employing the O_BCSM, and the processing is resumed according to the O_BCSM.
