Abstract: Novel tools and techniques are provided for implementing programmatical public switched telephone network (“PSTN”) trunking for cloud hosted applications. In various embodiments, a computing system may determine one or more first network interconnection characteristics associated with a first entity service provider within a call service network operated by a call network service provider. Based on the determined one or more first network interconnection characteristics associated with the first entity service provider, the computing system may cause a network provisioning application layer to establish one or more network interconnections between a first network associated with the first entity service provider and the call service network, in some cases, by establishing shared peering connections between the first network and the call service network.

Abstract: An acoustic sensor assembly includes a housing having an external-device interface and a sound port to an interior of the housing. An electro-acoustic transducer and an electrical circuit are disposed within the housing. The electro-acoustic transducer separates the interior into a front volume and a back volume, where the sound port acoustically couples the front volume to an exterior of the housing. The back volume includes a first portion and a second portion. The electrical circuit is electrically coupled to the electro-acoustic transducer and to the external-device interface. One or more apertures acoustically couple the first and second portions of the back volume and are structured to shape a frequency response of the acoustic sensor assembly.

Abstract: A server system including a plurality of servers achieves redundancy on a per process basis. A first server and a second server execute a plurality of processes in parallel. Processes (B1-1, B2-1, and Br-1) in the first server are active processes, and processes (B1-2, B2-2, and Br-2) in the second server are standby processes. The active process periodically transmits an operation notification notifying normal operation, to the standby process. When no longer receiving an operation notification from the active process, the standby process switches an operation mode of the standby process from a standby mode to an active mode and starts provision of service of the process. The process switching is performed on a per process basis instead of on a per server basis.
