186 How to Delete Call Records

Take Henan users as an example, you can customize the shredding list through the business hall or account manager:

Send a customized invitation message to a specific customer group through the system, informing customers that you can customize the shredding list in the business hall for free. If you customize this service, you will be restricted from querying all the phone bills (including call list, SMS list, gprs list, Monternet list, etc.) within the ordering time. If there is an email phone bill information service customized by the customer, it will be sent to the customer, but the customer cannot view the content.
