<section3 topic='Inbound Call' anchor='session-establishment-inbound'>
<p>When the system receives a call from one of its connected networks, it MUST then expose that requested session to Rayo clients. It SHOULD use an implementation-specific routing mechanism to map incoming calls to some set of registered JIDs which are considered appropriate controlling parties. From this set, it SHOULD then remove any parties whom it can identify as being temporarily inappropriate for control (either unavailable based on presence, under too much load, or any other metric which the server has available). If, as a result, the set of Potentially Controlling Parties is empty, the server MUST reject the call with a 'decline' reason.</p>

<p>If the server can identify active Potential Controlling Parties, it MUST offer them control of the call simultaneously. The server must broadcast an offer on behalf of the call to all Potential Controlling Parties, using applicable to/from/header data from the incoming session. The server MUST also include entity capabilities information in the presence stanza containing the offer, in order to advertise the fact that the entity is a call, qualified by the node name "urn:xmpp:rayo:call:1".</p>

<p>XMPP message stanzas directed to the call's JID with a type of 'normal' MAY be forwarded to the calling party by translating the message into the calling party's protocol. In the case of SIP, this SHOULD follow the conventions set out in <a href="http://tools.ietf.org/html/draft-ietf-stox-im-06">draft-ietf-stox-im-06</a> with the exception of the &lt;thread/&gt; to Call-ID mapping, as the Call-ID will always be that of the calling party.</p>
<p>If a message is directed to the call's JID with a type other than 'normal' then the server MUST return a &lt;feature-not-implemented/&gt; error with a type of 'modify'. If no translation is possible then the server SHOULD return the same error but with a type of 'cancel'.</p>
