Hi, friend!

CPIF (Calculated Planning Impairment Factor) value is an advantage factor and MOS (Mean Opinion Score) is an average estimatation of the VoIP performance.

MOS measures the subjective call quality for a call. MOS scores range from 1 for unacceptable to 5 for excellent. VOIP calls often are in the 3.5 to 4.2 range. The ITU P.861 (PSQM) and P.862 standards explain how to calculate MOS scores.

@user_3167337 you made a mistake, in your picture it's the MOS-CQ which equals to 438, not MOS.  If you want to learn more about this, please refer to https://www.telchemy.com/appnotes/TelchemyVoiceQualityMeasurement.pdf
