A call processing apparatus (SW) comprises a first queue (Q 1 ) for temporary storage of an incoming call and several parallel second queue systems (Q 21 -Q 23 ), each corresponding to a different recipient (R 1 -R 3 ). A recipient selection logic (RS) selects an optimal recipient for the call and terminates it after it has propagated through the first queue. The recipient selection logic then selects a second queue system (Q 21 -Q 23 ) that corresponds to the selected recipient (R 3 ). Instead of a real call, a virtual call corresponding to the incoming call is placed in the selected second queue system. A callback function (CF) and a call connection (CC) function detect the virtual call's propagation through the second queue system, and establish a callback call to the client (C 1 ), whereby an optimal recipient can be selected for the call and telecommunication resources are not consumed during waiting.
