<p style="font-size: 13px">Let's look at configuring Asterisk to receive MWI from other systems.</p>
<p style="font-size: 13px">Depending on your Asterisk version and configuration, there are a few different ways to configure receiving MWI from external sources.</p>

<li style="font-size: 13px"> <strong>chan_sip</strong>: outbound MWI subscriptions and receiving unsolicited MWI NOTIFY messages</li>
<li style="font-size: 13px"> <strong>res_external_mwi</strong>: A module providing an API for other systems to communicate MWI state to Asterisk</li>
