Audio Quality Test

The quality of your audio channel has a direct inflluence on the quality of your customer conversation.

Audio Quality Test

How does it work?

  • Spearline in-country server dials your toll/toll-free contact number. We use standard phone lines with ISDN signalling to replicate your customers’ experience.
  • Spearline server sends a DTMF tone which your IVR is configured to recognise (eg ‘9-8-7-5-7’)
  • IVR connects the test call to a pre-loaded audio (WAV) file. The WAV file is played back over the line, recorded on the Spearline server and then analyzed to generate an audio quality score.

Audio Quality Test

What is it?

The audio quality test enables you to replicate a customer’s call and generate objective industry-standard audio quality scores. With minimal setup, this test can provide a wealth of understanding about your customer’s experience, as well as the level of service being delivered by your carrier.

When is it used?

The audio quality test is used to proactively monitor the availability and quality of your global toll and toll-free numbers. It is used to gain real-time alerts on customer-impacting issues and to hold carriers to SLAs. In many cases, it is also used to demonstrate your quality standards to your customers using independent and objective measures.

What is measured?

  • Connection success or failure
  • Post dial delay (between the number being dialled and the call being answered)
  • DTMF (touch tone) functionality
  • IVR response
  • Audio quality
