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.
