Title:
OUTBOUND CALL FAILURE RESULT DETECTION METHOD BASED ON FREESWITCH AND ASR
Document Type and Number:
WIPO Patent Application WO/2022/206719
Kind Code:
A1
Abstract:
Disclosed in the present invention is an outbound call failure result detection method based on FreeSWITCH and ASR. The method comprises: step 1, recording a call process of a call service by means of FreeSWITCH, and generating recording record information; step 2, converting the received recording record information into text information by means of an ASR module, and classifying a dialing result on the basis of the state of the dialing result of a call and an analysis of keyword information; and step 3, identifying a correct dialing result according to a classification result, and feeding back the correct dialing result to a user automatic outbound call system. By means of the present invention, outbound call failure results such as "arrearage" and "unassigned phone number" can be directly acquired, and the deep-seated problem of failing to obtain a correct dialing result after a PSTN call is made is solved.
