I noticed that after last update (5.0.41) there is a problem with outbound route on CXE3000 .
Call to GSM should go trough 3 ISDN BRI Gateways and (if all BRI lines are busy) trough main sip trunk.
The problem is, when all BRI lines are busy on first trunk call never goes to the second trunk (sip) and fails.
