[VoiceOps] ATA To Connect to Mitel PBX

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