Hi Marlon
One thought is, the alerts rely on the PBX responding to and giving Prognosis the current status. Depending on the specifics there are ways to alert if last response was a long time ago, if the SAT connection was disconnected, if no ping reply, things like that. Theoretically, testing might involve finding a manually changeable setting on the PBX that has no impact and then making Prognosis alert on it.
If you open a case with IR Support they can assist you to consider the specifics of that particular alert.
