Description

A privacy number callback control method, system, device and storage medium in VoIP

technical field

The present invention relates to the technical field of communication, and more specifically, it relates to a method, system, equipment and storage medium for calling back a private number in VoIP.

Background technique

With the continuous development of communication services, people have higher and higher requirements for the quality of current calls. The full name of VoIP is voice over IP, which is a voice call technology that achieves voice calls and multimedia conferences through the Internet Protocol (IP). That is to communicate via the Internet. Therefore, VoIP users can use mobile data or WIFI to initiate voice calls directly to the peer through the mobile app. In real business scenarios, VoIP is often used to call each other between apps, such as WeChat voice, QQ voice, etc. However, with the popularization of the Internet, VoIP is also frequently used in scenarios where apps call out to landlines and directly dial the phone number of the opposite end (referred to as the landing call scene). The VoIP landing call scenario is often used in scenarios such as customer outbound marketing, express delivery or takeaway delivery, and business satisfaction return visits.

Because calls to landed line numbers are often limited by the risk of financial fraud and complaints, in order to improve the service connection rate, the Internet often binds the line and mobile phone number again when the VoIP landed line calls out. The called number is displayed as a mobile phone number, which can not only effectively improve the connection rate of outbound calls, but also effectively hide the real number of the calling party and the called party to prevent the real number of the calling party and the called party from leaking.

At present, the above-mentioned scenarios are relatively mature in the outbound call business scenario, but even in the outbound call business scenario of the nature of customer return visits, the called party often calls back. The current general solution is to call back to a fixed customer service number , but the fixed customer service number to answer the customer service cannot fully understand the customer's needs. Callback customer complaints may not be resolved. In the express delivery scenario, the callback needs to be accurately called back to the delivery personnel, so as to facilitate and quickly communicate on delivery matters.

Contents of the invention

The technical problem to be solved by the present invention is aimed at the above-mentioned deficiencies of the prior art. The first object of the present invention is to provide a method for controlling call-back of private numbers in VoIP.

Step S3. After the service agent layer completes the authentication, it confirms the call related information through the call control layer, and sends a call connection instruction to the communication network element layer;

Step S4. Send call connection SIP signaling to the landing line through the communication network element layer. After receiving the signaling, the calling line initiates service binding to the privacy number platform. If the binding is successful, it will return the corresponding intermediate number. At this time The line sends the call to the privacy number platform;

Step S5. Connect the call to the called party through the privacy number platform. At this time, the call has been established, and the media service layer is responsible for transmitting the voice stream and storing the recording;

Step S6. In the call release stage, the caller or called party initiates a hang-up instruction and sends it to the privacy number platform. After receiving the bye instruction, the privacy number platform sends the bye instruction to the line side, and the line transparently transmits the bye to the VoIP platform, and finally the call is released by the VoIP platform.

As a further improvement, when the calling party initiates an outbound call, the real calling bill information, real called bill information, and traffic id bill information are stored in the cache.

Further, when the call passes through the communication network element layer, the fixed-line information and the intermediate number information of the call landing are stored in the cache.

Furthermore, after the outbound call ends, if the real called party initiates a call back at this time, when the call reaches the VoIP platform, before connecting, the following connection strategies are included:

Strategy 1 is calling to a fixed line number;

Strategy 2 is to call to the real caller. To call to the real caller, the following tasks need to be completed: send a binding query request to the privacy number by using the intermediate number information and line number information in the cache. Caller information, after obtaining the original caller information, the call can be sent to the original caller, otherwise the call will be made to the fixed line number;

Strategy 3 is call ringing. First, the call is connected to the real caller. When the caller rings and fails to answer after the set time, the call is connected to the fixed line number; the process of connecting to the real caller is the same as strategy 2. .

Further, set the time to 10s.

Further, the VoIP platform side configures the connection strategy according to the different needs of the access users, and subsequent customer callbacks follow the configured callback strategy for call connection.
