    Unfortunately the MITEL tech is being very little help.š Even the
    customer says they are not-responsive.š So I have no way of knowing
    what the MITEL settings are now, he has not responded to my
    requests.š Previously they were getting POTS handoff from an
    AT&T T-1 to POTS unit, supposedly it worked fine.š <br>
    <br>
    This is at a Hotel, so getting the exact scenario that happens is a
    little difficult.š What we have been told is that randomly, an
    incoming call will route directly to a guest room.š We can't even
    get times when this happens to correlate call logs, as the guest
    just complains to the front desk at checkout.š The only thing we can
    figure, is that the MITEL is not closing a trunk line, and and if an
    incoming call hits that same trunk, it just rings through to the
    last extension connected to that trunk.šš <br>
    <br>
    Would there be any harm in turning the Forward Disconnect Delay up
    to it's maximum value?š I think 2000ms.š <br>
