問題：

為了防止卡線遭投訴被運營商停，給公司帶來損失，對一些特定號段特定區域要進行限制，不讓客戶呼出

打開VOS3000

落地網關——補充設置——落地被叫前綴——禁止

添加禁止號段

具體案例：

如填寫如下號碼段：

880130,880131,880132,880133,880145,880147,880149

,880153,880155,880156,880170,880171,880173,880175,

880176,880177,880180,880181,880185,880186,880189

,915010,9150130,9150131,9150132,9150133,9150145,

9150147,9150149,9150153,9150155,9150156,9150170,

9150171,9150173,9150175,9150176,9150177,9150180,
