An apparatus and methods are disclosed that enable a first user of a telecommunications terminal to receive, upon placing a call to a second user, a ringback signal that is based on information from one or more call logs. Such information might include: the number of times that the first user has attempted to call the second user during a particular time interval; the time of the most recent call from the second user to the first user; etc. A data-processing system (e.g., an originating switch, a terminating switch, a wireless base station, a server, etc.) that receives a call-setup signal consults one or more call logs and generates a ringback signal that is based on the contents of the logs. Such call logs might include a log for a telecommunications terminal, a log for a user, a log associated with a particular private branch exchange; etc.
