Abstract
A telecommunication network exchange and method of playing an announcement to a call party in a telephone exchange during connection set-up. The invention is based on the idea of totally separating the detection of the need for an announcement from playing the announcement. The need for the announcement is detected in a conventional manner at a given stage of call set-up. However, the exchange does not play the announcement immediately, but delays playing it up to a later stage of call set-up or up to a later event, if necessary. The announcement may be played, for example, not until collection of additional dialing is definitely terminated, the call is confirmed to be successful, the announcement is confirmed to be necessary/correct, and so on. As a consequence of the delayed playing of the announcement, wrong and unnecessary announcements and the failure of the call are thus avoided.
