Abstract

The present invention relates to a telecommunications exchange (1) and a method for handling call diversions such that emergence of so-called trombone connections is avoided. According to the inventive telecommunications exchange (1) and method, trombone connections are avoided by means of changing a diversion of calls placed to a first extension number (No(V)) in the exchange, from being diverted to a second remote extension number (No(A)), which is used to set up a data connection (15), to instead be diverted to a predetermined third extension number (No(S)). An advantage of the present invention is that connections that previously unnecessarily used three trunk channels, by means of the invention instead are set up on a single trunk channel. Thereby available trunk resources are utilized more efficiently in a telecommunications system.
