400电话的彩铃就像我们平时用的手机一样，如果我们的手机想要换个彩铃，我们必须也要到营业厅办理这个业务选择自己喜欢的铃声。然而我们都知道，我们手机更换彩铃是收费的项目。400电话也是如此，唯一不同的是我们400电话的彩铃是根据您公司要求自己制作的，我们需要专门请人帮您制作最适合您公司形象的彩铃，比如欢迎词、公司简介之类的。
The ring tone of 400 telephone is the same as that of our normal mobile phone. If our mobile phone wants to change a ring tone, we must also go to the business hall to handle this business and choose the ring tone we like. However, as we all know, it's a fee for us to change the RBT. The same is true for the 400 telephone. The only difference is that the color ring of our 400 telephone is made according to your company's requirements. We need someone to help you make the most suitable color ring for your company's image, such as welcome words, company profile and so on.
而且需要向您说明的是这个费用也不是我们公司收取，我们公司同样是请专业的制作人员录制的，这个是可以录制到您满意为止的。
What's more, we need to explain to you that this fee is not charged by our company. Our company also asks professional producers to record it, which can be recorded to your satisfaction.
