I used one E1 with switchtype=euroisdn signalling=pri_cpe 
connected to C&C08 Huawei Local eXchange.All supplementary services are enabled in LX.

How about Disconnect message after facility message ? I changed parameter: 
|cfb|cfnr|unknown but always Asterisk send Disconnect message with 
"Subscriber Absent" cause. DAHDISendCallreroutingFacility sends Disconnect message?
maybe this cause is why LX don't do anything.

ok I will do but I am not sure about add always "Cause value=Subscriber Absent" to bug report or not.
