First Claim
Patent Images
1. A method for doing call classification on a call to a destination endpoint, comprising the steps of:
- receiving audio information from the destination endpoint;
concurrently analyzing using automatic speech recognition the received audio information for a first type of classification and a second type of classification; and
determining a call classification for the destination endpoint in response to the step of analyzing.
