The structure of the intelligent outbound call is as follows能外呼的结构如下图：

After the call is successfully sent, the on-hook detection control module bypasses the voice to the recognition engine, and the recognition engine determines the voice type of the far end to identify whether the remote end is busy. If it is busy, directly hangs the call and gives the reason for the hang up.


Use scenario 1: Batch outbound to improve efficiency

In the case that the called terminal is in a call or is not able to be turned off, the operator will usually play the prompt tone "Sorry, the user you dialed...", and will not immediately give the back signal to the hook, this prompt The tone may last for 1 minute.

The Yihang identification module can recognize that the call needs to be released when the prompt sounds "busy" or "shut down", thus shortening the invalid occupancy of the channel from several tens of s to several s, and multiplying the utilization of the line.

Use scenario 2: number status recognition

The operator may prompt to delete the invalid number, fax, etc. from the number database according to the reason that the connection cannot be made.

Use scenario 3: Accurate redial

The app can schedule subsequent redials based on reasons that cannot be reached, to avoid missing critical notifications.

Use scenario four: intelligent gateway

This feature can be built into the gateway to greatly increase the utilization of the gateway line.
