A call log associated with outgoing calls originating from calling devices may be established and maintained. Filter parameters may be set to specify which outgoing calls to log. Outgoing call information associated with calls originating from a user's calling devices may be obtained and transmitted to a service center. A server in the service center may determine whether or not to log the outgoing call information based on the filter settings. The outgoing call information may be stored in the call log, which may reside in a database in the service center. The user may access the call log from a user terminal and/or the calling devices. The call log may be used to add contacts to a contact list and facilitate data analyses.
