Abstract: A method for monitoring an operation of a plurality of devices is provided. The method includes receiving, from each of the plurality of devices, a signal representative of a parameter indicative of a current condition of a respective device, comparing each of the parameters to a computational model, determining, for each of a plurality of time periods, a probability each of the plurality of devices may fail based on the comparing, and scheduling maintenance if a quantity of the plurality of devices likely to fail in one of the plurality of time periods exceeds a quantity threshold level.

Abstract: A called party may screen for a telemarketing solicitation made by a calling party by receiving a traditional telephony call from the calling party at a messaging service platform and using the messaging service platform to perform telemarketer-screening operations. These telemarketer-screening operations may use a telemarketer blacklist and an associated whitelist in processing the traditional telephony call. When the traditional telephony call is not processed using the telemarketer blacklist or the associated whitelist, the calling party may be challenged to identify themselves. The called party may react to the traditional telephony call by selecting a call processing option that enables the traditional telephony call to be processed as a nontelemarketing telephony call, processed as a telemarketing telephony call, or added to the associated whitelist.
