Step 306: According to the prompt tone of the voice navigation, if the user dials the number transferred to the manual server, then according to the number information function list of the voice navigation, the call is connected to the manual agent.

Step 307: If the user directly dials an extension number, the call is connected to the extension. For example, if the user knows that the phone number of the finance department is 4405, the user directly dials 4405 to connect to the phone number of the finance department. If the number information function of the voice navigation is set to correspond to an extension, the user can also dial a number to transfer to the extension. For example, listen to the navigation prompt "Please dial 2 for flight inquiries", then dial 2 to transfer to the responsible person. An extension of the flight advisory.

Step 308: If the user dials the number connected to the voice interaction platform after listening to the voice prompt, the call will be connected to the language interaction platform, such as to the enterprise voice mailbox for leaving a message.

Step 309: If the user dials the number for entering the next floor after listening to the prompt tone, the call is connected to the voice guidance for the next floor.

Steps 310 and 311: the VIP client server instructs the VIP client media server to play the navigation sound of the second-level voice navigation, and start receiving numbers at the same time.

Step 312: If the user dials the number transferred to the upper layer, the call is transferred to the upper layer voice navigation. Similarly, if you dial the corresponding number, you can also transfer to the extension, transfer to the next floor, transfer to the upper floor, transfer to manual service, and transfer to the voice interaction platform function, which will not be described here.

Step 313 : Play the voice navigation prompt tone of the upper layer, and restart the navigation according to the navigation information set in the upper layer.

Step 314: If the user dials the phone number transferred to the next floor, the navigation prompt tone of the next floor will be played, and the user dials the corresponding number according to the voice prompt, and the extension, the next floor, and the previous floor can be implemented respectively , transfer to manual service, transfer to the functions of the voice interaction platform, in this embodiment, multi-layer navigation nesting can be supported.

It should be noted that after step 302, if the nature of the call is an intra-group call, the welcome words and slogans of the users in the group will be played, and the navigation tone of the users in the group will be played. Number. The specific steps are the same as those of the out-of-group call, and will not be repeated here.
