<p>For each candidate received, the other party acknowledges receipt or returns an error:</p>

|

<p>At the same time (i.e., immediately after acknowledging the session-initation request, not waiting for the initiator to begin or finish sending candidates), the responder also begins sending candidates that may work for it. As above, the initiator acknowledges receipt of the candidates.</p>
|
||||
<p>As the initiator and responder receive candidates, they probe the various candidate transports for connectivity. In performing these connectivity checks, the parties follow the procedure specified in Section 7 of <cite>draft-ietf-mmusic-ice</cite>.</p>
|
||||
<p>If one of the candidate transports is found to work, the responder accepts the session.</p>
|
||||
<p>Because the parties have chosen the Jingle ICE-UDP Transport Method, the initiator and responder exchange an open-ended number of possible candidate transports, perform connectivity checks, and agree upon a candidate transport as explained in <cite>XEP-0176</cite>. Once one of the candidate transports is found to work, the responder accepts the session.</p>
