<p class="MsoNormal"><span lang="EN-US">Ranking the calls by origCause_code (or destCause_code) I am seeing the Disconnect Cause code 86 as the third most frequent termination cause (17985 calls), behind Normal Call Clearing (97221) and No Error (51801), and
the next reason is Split Call (15766)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">According to Cisco´s docs, the code corresponds to:<o:p></o:p></span></p>

This cause indicates that the network has received a call resume request containing a Call identity information element indicating a suspended call that has in the meantime been cleared while suspended (either by network time-out or by the remote user).<br>
