There is disclosed a system for managing calls between parties in a telecommunication network, the system comprising a database (16, 33) having a plurality of records, at least some of the records defining at least one ring time out parameter (RTP), each RTP specifying when a call will be terminated without called party intervention, database checking means (12) for checking the database in response to a calling subscriber initiating a call to a called party to determine whether there is a record that defines an RTP for said called party and retrieving the RTP if an RTP is defined, and call stopping means (13) for stopping the call on the basis of the retrieved RTP if stopping the call is necessary to avoid termination without called party intervention.
