NetBorder Call Analyzer Answering Machine Detection - Customizing Detection Type

Table of Contents

To increase speed of the detection you may want to disable the AMD and/or end of greeting detection (700-1900hz tone). The downside to this is of course there will be no AMD or end of greeting detection, so it would only be used in certain cases. 

1. Depending on your mode edit the correct file listed below:

     CallAnalyzerAsOutboundProxy.call-properties
     CallAnalyzerGenesysOCS.call-properties 

2. Change "app.nca.ExpectPhoneNumberPrefix=false" to "app.nca.ExpectPhoneNumberPrefix=true"

3. Save and restart NCA

1. NCA will now be expecting a prefix of "991x" with x being one of the values listed in the table below.

2. In your dialer configure the correct prefix to be sent. For an example if you would like to Enable AMD but disabled end of greeting then send the prefix "

9911". So if you were calling Sangoma the total number would be "991119054741990". NCA will stip the "9111" from the begining of the number and send out "19054741990" to your SIP proxy/ITSP.
