An auto-dialler is a piece of electronic equipment that reports the alarm status of a device such as a vaccine fridge. The alarm may be delivered in the form of a Voice phone call, SMS, Email or a Pager message.

Traditional auto-diallers plug into an analogue phone line. However, with the introduction of the National Broadband Network and the associated demise of analogue phone lines, auto-diallers have largely disappeared as a means of receiving alerts. Now for an auto-dialler to function, it will need a way to connect to a 3G or 4G network, and this is something that ENLAKE can help you out with.
