Factors that measure call scoring within Observer Analyzer can be customized depending upon the netwok's specific VoIP equipment and overall network characteristics. For example, VoIP calls made on the factory floor may be scored differently than a call made within a small, quiet office.

Quality score impairment factors include:

  • Loudness rating
  • Talker Echo Loudness Rating
  • Circuit noise
  • Floor noise
  • Coding and decoding delay
