現在，已經有越來越多的企業開始使用400電話了，但是還有些人對400電話不夠了解，下面這些知識能夠讓你更好的認識400電話。
Now, more and more enterprises have started to use 400 phones, but some people do not know enough about 400 phones. The following knowledge can help you better understand 400 phones.
一、400電話并不是免費電話，有些人把400電話和800電話混淆。800電話是免費的，但是太僅是支持座機撥打。如果用手機撥打的話會被提示是空號。而400電話是在800電話的基礎上設計出來的，太是升級版本。不過400電話并不是免費的。撥打400電話的手機或者座機都需要支付市話費用，所以大家不要把400電話誤以為是免費電話。
1、 400 is not a toll free number. Some people confuse 400 with 800. The 800 phone is free, but it only supports dialing from a landline. If you dial from your mobile phone, you will be prompted that the number is empty. The 400 phone is designed on the basis of the 800 phone, which is an upgraded version. But 400 phone calls are not free. Mobile phones or landlines that dial 400 calls need to pay for local calls, so don't mistake 400 calls for free calls.
二、400電話接聽也需要收費。400電話是雙邊收費的，也就是用戶撥打電話需要承擔市話費用，同時企業也是需要支付的。如果電話都免費的話，這樣運營商就沒辦法賺錢了，所以這肯定是不可能的。
2、 400 calls are also charged. 400 calls are charged bilaterally, that is, users need to bear the local call fees when making calls, and enterprises also need to pay. If the phone is free, the operator will not be able to make money, so this is definitely impossible.
三、選擇400號碼一定要選擇一個的號碼?，F在市場上有很多二手的400電話，二手400電話號碼都是比較靚的，很多人都愿意選購400號碼。但是選擇400電話也有弊端，一旦辦理二手號，那么可能會接到騷擾電話。
3、 When selecting 400 numbers, you must select a number. Now there are many second-hand 400 phones in the market. The second-hand 400 phone numbers are quite beautiful, and many people are willing to buy 400 numbers. However, there are also disadvantages in choosing 400 phone numbers. Once the second-hand number is handled, you may receive harassing calls.
四、400電話辦理對象是有限制的，只能是公司或者個體會辦理，個人是沒辦法辦理的。甚至可以說400電話就是企業專用電話。它不歸屬于某一個人，智能歸屬于企事業單位。
4、 There is a limit to the objects of telephone handling, which can only be handled by companies or individuals. Individuals cannot handle it. It can even be said that the 400 telephone is a special telephone for enterprises. It does not belong to a person, but intelligence belongs to enterprises and institutions.
五、400電話只能夠接聽不能夠撥打。400電話是沒辦法撥號的，如果你接到了400的來電，那么這個已經不是400電話了，而是網絡電話。這種行為在行業內是違規的，如果被查出來是會被封號的。
5、 400 calls can only be answered but not dialed. 400 calls cannot be dialed. If you receive a call from 400, it is not a 400 call, but an internet call. This kind of behavior is illegal in the industry, and will be banned if found out.
六、400電話如何安裝。400電話是不需要安裝任何設備的，只要是能夠接聽的電話綁定在400電話上便可以使用了。但是申請400電話一定要提供相關的資料。包括企業營業執照和身份證掃描件，以及400電話申請單等等。申請開通400電話是不需要收取任何費用的，但是使用400電話就要收費了。
6、 400 How to install the telephone. The 400 phone does not need to install any equipment, as long as the phone that can be answered is bound to the 400 phone. However, you must provide relevant information when applying for 400 telephone calls. Including the scanning copy of the business license and ID card of the enterprise, and the 400 telephone application form, etc. There is no charge for opening a 400 phone, but there is a charge for using a 400 phone.

八、400電話的使用，使用400電話是一定要有企業彩鈴的，這樣有利于塑造企業良好的形象。還有400電話轉接好有2部以上的電話，這樣能夠解決占線的問題。企業要把自己的400號碼宣傳出去，這樣會有更多的人知道和使用在這個號。
8、 The use of 400 telephone must be accompanied by enterprise RBT, which is conducive to shaping a good image of the enterprise.
