    From what we are told, an incoming call, instead of ringing the
    front desk, rings directly to a guest room.š A very few number of
    calls appear to do this, and it's not always the same room.š We hear
    about this happening in the middle of the night, but of course
    that's when someone is in the room to hear it.š Without any time
    stamps of when this happens, I'm not able to answer the Trunk order
    question, and being 3 times removed the from the information (Guest
    -> Front Desk -> Hotel Management -> Me) getting more
    specific detail is hard.š I always ring inbound lines starting with
    1, but it appears that outbound calls from the MITEL round robin the
    trunk lines.š When I place test calls to/from the hotel when I'm on
    site, I can't replicate a trunk port staying open (by looking at the
    LED's on the front of the MITEL card), but that's the only
    explanation that makes sense so far.ššš <br>
    <br>
    I just added a ground wire between the adtran and the Mitel (they
    previously had a common electrical ground).š I'm hopeful that the
    MITEL Tech will respond to some of my inquiries for information.š <br>

          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
