What if the title is called? How to solve

The calling is because the Ministry of Industry and Information Technology stipulates that individuals are not allowed to make business calls when they apply for cards, and strange numbers that are called out at high frequency will be blocked by operators. At present, the best solution is to use the dial-out system to avoid the card number being blocked.

The callback system can understand it.

It is through the system transfer mode, through the system dialing, your business mobile phone is only connected with the line phone, so that there will be no strange numbers called out at high frequency, and customers can also call back the business mobile phone number and take away the number filtering. For customers who like to complain, the system will automatically filter, and it is recommended not to call this service.

Generally speaking, which scheme to adopt depends on the situation of the enterprise and the appropriate telephone system is selected.
