<p>In this example, a call from 'tel:+13058881212' has reached the Rayo server 'shakespeare.lit' by calling 'tel:+18003211212', and been assigned an ID '9f00061'. The server has determined that 'juliet@capulet.lit' is a valid candidate for delegating control of the call, and so has directed an <a href='def-offer'>offer event</a> to her 'balcony' resource.</p>
