提示您拨打的电话是空号。
The number you dialed is empty.
拨打的电话不存在，我们可以在绑定电话自己测试，分别拨打400及目的码看是否能正常转接到绑定电话上，再到平台转接日志里面查看相应的流程提示。拨打400号码提示空号，或号码不存在，如果没进平台，一般是由于主叫方运营商对400号码做了数据限制，可电话联系主叫方运营商进行投诉，该问题能投诉处理好（注：由于电信4009号段对铁通做了限制，所以现在所有铁通号码都无法拨打电信4009号段，该问题需注意，要事先跟用户做相应的解释处理）由于安徽合肥落地问题，现长春、武汉及北方部分区域开在合肥落地会直接提示号码不存在，需要拆机处理。
Calls do not exist, we can test in the bound phone itself, dial 400 and the destination code to see whether the normal transfer to the bound phone, and then to the platform transfer log to see the corresponding process hints. Call 400 number to indicate empty number, or no number exists. If you do not enter the platform, it is generally because the calling operator has made data restrictions on the 400 number, you can contact the calling operator to complain. This problem can be handled well. (Note: Because of the restrictions imposed on Tietong by paragraph 4009 of Telecom, all Tietong numbers can not dial Tietong 4009 now. This problem needs to be noted. Due to the landing problem in Hefei, Anhui Province, some areas in Changchun, Wuhan and the north of Hefei will directly indicate that the landing number does not exist and need to be dismantled.
