How Do I Solve the Problem that a Call Number Is Marked as a Harassing Call Number by a Customer?

If your call center frequently calls unknown customers to promote services or products, or your calls are meaningless to customers, customers will mark the call numbers as harassing calls to avoid harassment. Most customers will reject calls from unknown numbers. You can verify your phone numbers on a phone authentication platform such as 360.cn or dianhua.cn. Huawei can cooperate with you to file a complaint, for example, provide related proof documents. The complaint result is subject to the handling conclusion of each platform.

What Types of Numbers and Lines Can Be Interconnected with the CEC?

The CEC supports only SIP interconnection. Therefore, only lines that fully support SIP can be interconnected with the CEC.
