Avaya trunk group disconnect supervison

[navy1]

Set up trunk group for inbound toll free. Circuits are ISDN-PRI.

What is rule of thumb regarding how to option "disconnect supervision" on trunk group form? Below is how my trunk group is set up.

Group Type: isdn
TRUNK PARAMETERS
Disconnect Supervision - In? y Out? n
Answer Supervision Timeout: 0

Also, does anyone know what are some issues you'd encounter with incoming calls if you optioned your disconnect supervision incorrectly? Thanks for any advice.

You may wish to try the Avaya forum.

I don't see any reason why you would ever NOT want disconnect supervision for both in and out. If either side abandons the call surely you want to free up the trunk no matter who placed the call.

Good Luck.
