best of times. Disconnect supervision on FXO is more of a best-effort attempt than an actual thing.<br>
<br>
If the disconnect signal is properly interpreted by the gateway then like you I would expect the gateway to end that leg of the call regardless of SIP reachability. But I consider that a pretty big if!<br>

<p class="MsoNormal">Hi Folks, <u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">If the voice gateway is defined with disconnect tone/ cadence,etc. Should a loss of connectivity (SIP signaling between VG and CUCM) cause the FXO port not to hang up ?

<p class="MsoNormal">To me , SIP is peer to peer signaling. It should not affect the voice gateway decision for going on-hook when a disconnect tone is detected even there is a loss of connectivity to CUCM.
