<p class="MsoNormal"><span style="color:#404040">I would also suggest debugging the signaling protocol being used for calls to/from this analog port or reviewing CCM SDI/SDL traces. If these are MGCP controlled, try to determine if CUCM transmitted a DLCX without
<b>first</b> receiving a NTFY for the on-hook event (O: L/hu). Seeing a NTFY with O: (observed event) L/hu (line package/on-hook transition) come into CUCM from the gateway for your analog endpoint hung up -- if a DLCX to the gateway follows that event, then
the disconnect was initiated from the analog endpoint.<o:p></o:p></span></p>
