Spearline uses DTMF tones to navigate your IVR system to a pre-loaded audio WAV file. This is then measured based on how much the signal degraded from the original.
- The Spearline in-country server dials your Toll or Toll-Free contact number using SIP or standard ISDN phone lines provided by local carriers in-country (this replicates your customer’s experience).
- Once connected, Spearline sends a DTMF tone which your IVR system is configured to recognize. Using this, the IVR connects the call to a pre-loaded audio WAV file which is then played over the line.
- The audio is recorded on the Spearline server and then analyzed to generate an audio quality score.
- When issues are found, Spearline alerts you immediately and provides you with the call detail records needed to have the issues resolved.
