Fig. 1 is a schematic flow chart of a method for automatic line switching according to the present invention, and as shown in fig. 1, the method of the present invention has the following steps:
s101, the voice robot selects a gateway address from a gateway address list, and sends a call request to a gateway according to the selected gateway address, wherein the call request comprises a communication number of the voice robot and a communication number of a called user.
In this embodiment, the gateway is a third-party agent, and the voice robot calls the user through the third-party agent. Addresses of a plurality of third party agents are recorded in a gateway address list.
In this embodiment, when initiating a call, the voice robot selects a third-party agent from the gateway address list and sends a call request to the third-party agent, where the call request includes the telephone number of the voice robot and the telephone number of the called party. And after receiving the call request sent by the voice robot, the third-party agent analyzes the call request and extracts the telephone number of the voice robot and the telephone number of the called user.
S102, the voice robot receives link state information of the called user, which is sent by the gateway, wherein the link state information comprises normal link and abnormal link, and if the link state information is normal link, the voice robot receives a call initiated by the gateway and communicates with the called user.
On the basis of the above technical solution, further, the receiving of the call state information sent by the gateway specifically includes: the gateway initiates a call to the called user according to the communication number of the called user, initiates a call to the voice robot according to the communication number of the voice robot, and returns call state information to the voice robot according to the link establishment condition.
In this embodiment, the third party agent initiates a call to the user according to the phone number of the called user, and establishes a link with the user. And initiating a call to the voice robot according to the telephone number of the voice robot, and establishing a link with the voice robot.

The prompt tone is a ringing tone of the user indicating that the link is successfully established.
If the user is answering the call, or the user hangs up after ringing, or no answer is given after ringing, then the circuit will return prompt tones such as "call you dial is calling again later", "call you dial user temporarily has no answer to call again later", etc., this condition is also a successful link establishment. At this time, although the user does not answer the call, the link between the third-party agent and the user is already established, and harassment may be caused to the user if a new third-party agent is switched to make a call to the user again, so that the situations also belong to successful link establishment, and the voice robot judges whether to initiate the call again according to the situations.

In this embodiment, the third-party agent sets a temporary number, and uses the temporary number to call the user, and after the link between the third-party agent and the user is successfully established, uses the number of the voice robot to replace the temporary number, and at this time, the incoming call number displayed by the mobile phone of the user is the number of the voice robot. And after the third-party agent is linked with the link of the voice robot and the link of the user, the third-party agent exits the link.
On the basis of the technical scheme, further, the gateway judges whether the link is established successfully according to the response signal returned by the called user client.
On the basis of the technical scheme, further, the gateway judges whether the link is established successfully according to the voice signal returned by the called user client.

The prompt tone is a ringing tone of the user indicating that the link is successfully established.
If the user is answering the call, or the user hangs up after ringing, or no answer is given after ringing, then the circuit will return prompt tones such as "call you dial is calling again later", "call you dial user temporarily has no answer to call again later", etc., this condition is also a successful link establishment. At this time, although the user does not answer the call, the link between the third-party agent and the user is already established, and harassment may be caused to the user if a new third-party agent is switched to make a call to the user again, so that the situations also belong to successful link establishment, and the voice robot judges whether to initiate the call again according to the situations.
