<title>Jingle Message Initiation</title>
|
||||
<abstract>This specification provides a way for the initiator of a Jingle session to propose sending an invitation in an XMPP message stanza, thus taking advantage of message delivery semantics instead of sending IQ stanzas to all of the responder's online resources or choosing a particular online resource.</abstract>

<p>Because &xep0166; uses &IQ; stanzas for all interactions between the parties to a session, when sending an invitation the initiator needs to either pick one of the responder's resources (e.g., based on &xep0115; information) or send the invitation to all of the responder's resources that support Jingle. The first method is prone to error (e.g., in cases where more than one resource supports Jingle) and the second method requires sending a separate invitation to each resource. Neither of these is ideal. Although &xep0276; proposed a way to overcome the problem, it too has issues (e.g., dependency on a presence service and the need to reveal all supported XMPP features) and in any case has not been widely implemented.</p>

<p>This document proposes an alternative solution: exchanging a &MESSAGE; stanza before sending the Jingle invitation in an &IQ; stanza. (Indeed, in the early discussions leading up to the Jingle protocol the authors considered using &MESSAGE; stanzas instead of &IQ; stanzas, but chose the latter for their deterministic handling semantics.) This method effectively results in a kind of decloaking for Jingle purposes.</p>
