You are right, I missed the one bracket.

Yes, but we need to allow for 30,6 6,1 60,30 billing. I think the
easiest/best way to handle this is the connect charges as ASTCC
presently supports them.

I don't think it does. The 30 seconds come out because that is the
amount included in the connect charge. The connect charge is added back
in here:
$cost = ($billseconds / 60) * $adjcost + $adjconn;
