Abstract: A monitoring system for mitigating reporting delays between a customer device and a central monitoring station (CMS), for example, over a public switched telephone network (PSTN) may include a message tone detector, an acknowledgement tone detector, an acknowledgement tone generator and a processor coupled to each of the message tone detector, the acknowledgement tone detectors and the acknowledgement tone generator. The message tone detector may be configured to monitor one or more messages sent from the customer device to the CMS. The acknowledgement tone detector may be configured to monitor one or more acknowledgements sent from the CMS to the customer device in response to each of the one or more messages, respectively. The acknowledgement tone generator may be configured to generate and transmit one or more additional acknowledgements to the customer device when two consecutive messages of the one or more messages are substantially similar.

Abstract: A monitoring system for communicating between a customer device operating in a tone-based reporting format and a central monitoring station (CMS) operating in an IP-based reporting format may include a message tone detector, an IP message generator, an IP acknowledgement detector, a handshake and acknowledgement tone generator, and a processor communicatively linked with each. The message tone detector may be configured to intercept one or more messages sent from the customer device towards the CMS. The IP message generator may be configured to generate and transmit a converted message to the CMS. The IP acknowledgement detector may be configured to receive one or more acknowledgements sent from the CMS. The handshake and acknowledgement tone generator may be configured to generate and transmit one or more acknowledgements to the customer device based on a received acknowledgement from the CMS.
