<div class="content"><p>The LINE_MONITORDIGITS packet is sent when a digit is
detected. The sending of this packet is controlled with the <a href="8976b0d8-a50b-4671-b074-4aba9795566f" data-linktype="relative-path">MonitorDigits</a> packet. The
LINE_MONITORDIGITS packet is sent if the client has enabled digit monitoring.</p><table>
