<div class="content"><p>The LINE_MONITORMEDIA packet is sent when a change in the
media type of the call is detected. The sending of this packet is controlled
with the <a href="faab4393-16ae-4c34-8e76-72471452e3e8" data-linktype="relative-path">MonitorMedia</a>
packet.  The LINE_MONITORMEDIA packet is sent if the client has enabled media
monitoring for the media type detected.</p><table>
