I am pretty new to Asterisk so please be forgiving.
I am really impressed by FOP2 so we decided to buy it. I know that when I had the buttons auto configured the ZAP/DADHI trunk never showed as being in use.
In freepbx it list a PRI trunk as being ZAP/g0 (DADHI compatability mode) . Dadhi is installed and in use on the sytem.
Running the script to create buttons it creates
[DADHI/1]
type=trunk
label=DADHI
channel=DADHI/30
channel=DADHI/31
What is the correct setup for this trunk? DADHI or ZAP?
