Abstract: A method comprises: by a controller to communicate with devices of a network, storing classifiers assigned to groups of the devices to identify device commonality for each group; associating, to the classifiers, historical probabilities of success with which an automated response executed by one or more of the devices remediates a device alarm event; when a device of the devices reports the device alarm event, identifying each classifier to which the device belongs, each historical probability for each classifier, and a rule with classifier thresholds for the automated response; determining to execute the automated response on the device by evaluating the rule using each historical probability and the classifier thresholds; after the automated response is executed, performing a service test supported across the devices, and monitoring test results from the service test; and after the service test, updating each historical probability using the test results.

Abstract: A communication device, such as a Voice over Internet Protocol (VoIP) gateway, determines a duration for Dual Tone Multi-Frequency (DTMF) tone portions of telephony signal. If the duration is less than a pre-determined amount, a minimum duration is enforced during DTMF playback at a remote end of a network connection connected to a destination gateway. Minimum playback duration can be enforced at the terminating gateway—however, the originatinggateway can also encode a DTMF packet with a minimum duration value. At the terminating receiver it is not always possible to playback exactly what happened at the originating point in the same time frame. One solution to is to, at the terminating gateway, drop the first portion of voice packets that overlap with the end portion of played back DTMF tones.
