Certain aspects of the disclosure are directed to contact center management, using a data communications server. According to a specific example, the data communications server includes one or more computer processor circuits coupled to memory circuits and configured to interface with a plurality of remotely-situated client entities. The data communications server may be configured and arranged to monitor a plurality of communications placed to target recipients in a first communications-based campaign of a first client entity among the plurality of remotely-situated client entities, and to determine a disposition of each of the plurality of communications based at least on data received and relating to the plurality of communications. Based at least in part on the disposition of the plurality of communications from the first communications-based campaign, data communications server may generate a contact list of target recipients for a second communications-based campaign associated with a second remotely-situated client entity.
