爲什麽400電(diàn)話(huà)打不通？ Why can't the 400 phone get th

有客戶反應，有時候有400電(diàn)話(huà)打不通的情況，一(yī)般是以下(xià)幾種情況：

There are customer reactions, sometimes there are 400 phone calls that can not get through, usually in the following situations:

1）号碼占線或無法接通（欠費(fèi)、關機、不在服務區、手機壞了等等）    
2）綁定号碼錯誤。部分(fēn)手機号碼需要加區号    
3）設置的呼叫等待時間過短，一(yī)般需要設置15秒或更長，但所有号碼的呼叫等待總時間不 超過60秒    
4）400号碼欠費(fèi)（将聽(tīng)到欠費(fèi)提示音）    
5） 主叫在黑名單内，或設置了白(bái)名單但未包括此主叫（将聽(tīng)到無權撥打提示音）    
6）綁定号碼設置了可接聽(tīng)/不可接聽(tīng)區域，    
7）接聽(tīng)時段設置錯誤

1) The number is busy or can not be connected (arrears, shutdown, not in the service area, mobile phone broken, etc.)
2) Binding number error. Some mobile phone numbers need area code
3) Set the call waiting time is too short, generally need to set 15 seconds or longer, but the total call waiting time for all numbers is not more than 60 seconds
4) 400 number arrears (will hear arrears prompt sound)
5) caller in the blacklist, or set a white list but does not include this caller (Hearing the unauthorized dialing tone)
6) Binding number set up the accessible / unacceptable area,
7) wrong answer time setting
