Our LEC trunk lines are programmed to routinely block outbound calls. We need to be able to unblock some of these when we try calling a number that won't accept blocked calls. The LEC recording says to dial *82 prior to placing the call, but this is not recognized by our PBX. Is there a Fujitsu 9600 code that will perform this function? We've tried dialing "9" for an outside line, then *82 but that doesn't work, nor does *82 first.
