  • Patent number: 10708159
    Abstract: A system includes a plurality of SIP servers that are configured and arranged to provide services for a respective set of endpoints. A monitor server having at least one processor circuit receives connectivity status of the respective set of endpoint devices based on registration status provided by the endpoints to the SIP servers. Based upon the received connectivity status, endpoints having connectivity problems are parsed into subgroups. Based upon the parsed endpoints, potential problem sources for the connectivity problems of the parsed endpoints are identified. A monitor device having at LAN interface circuit connected to the LAN and at least one processor circuit receives the command from the monitor server and performs a diagnostic test on the LAN. Results from the at least one diagnostic test are provided to the monitor server.

  • Patent number: 10708440
    Abstract: Apparatus and methods are disclosed for display dependent analysis of call data in an IBPX. In an example embodiment, an apparatus communicatively coupled to an IPBX server is configured to route VoIP calls in the IPBX. An interface circuit is configured to selected parameters of interest based on capabilities of a set of devices and generate subscription requests to subscribe the devices to the parameters of interest. A first processing circuit is configured to generate call summary metrics from call event messages for calls routed by the IPBX server. A second processing circuit subscribes a device identified in the subscription request to the selected set of parameters of interest identified in the subscription request.

  • Patent number: 10666532
    Abstract: A system includes Session-Initiation-Protocol (SIP) servers that provide services for a respective set of endpoints. A monitor server can receive connectivity status of the respective set of endpoints based on registration status provided by the endpoints to the SIP servers. Based upon the received connectivity status, endpoints having connectivity problems are parsed into one or more subgroups. Potential problem sources are identified for the connectivity problems of the parsed endpoints. For each of the subgroups, the monitor server determines whether the subgroup exceeds a corresponding trigger threshold. In response a corresponding trigger threshold being exceeded, an action profile specifying an entity is accessed. A notification is transmitted to the entity.
