Abstract
The invention relates to a method of redialing in telecommunication networks for a call back when not engaged, whereby a caller carries out a call attempt to reach a callee, whereby the callee does not respond at firs. According to the invention, the callee may be reached without the caller having to continually undertake a further call attempt, whereby a radialling is automatically carried out by the relevant exchange within a given time window at given time periods and a connection to the callee is established should the same respond.
