400电话可以外拨显示400吗？
Can 400 phones be dialed out to show 400?
400电话既然可以接听来电，那么是否可以外拨呢？一般按照正常的逻辑思维哦，既然可以接，就可以跟手机、固话似的往外拨打。这样理解就错了，400就是虚拟号码，真正的号码还是我们的手机、固话等接听号码，所以400电话是无法往外拨打的。
Since 400 phones can receive calls, can they be dialed out? Usually in accordance with the normal logical thinking, oh, since it is acceptable, you can dial out like a cell phone, fixed-line. That's wrong. 400 is a virtual number. The real number is our mobile phone, fixed phone and other answering numbers, so 400 calls can't be dialed out.
