        <h2>Local Call example</h2>
        This example shows how to connect two <a href="https://get.cct.ericsson.net/latest/docs/reference/Client.html">clients</a> together through a <a href="https://get.cct.ericsson.net/latest/docs/reference/Room.html">room</a>. Once they both have joined the room, a peer-2-peer WebRTC <a href="https://get.cct.ericsson.net/latest/docs/reference/Room.html#startCall__anchor">call</a> is set up.
