This guide is part of our series on AI call scoring.

The call audit process in a BPO is the systematic framework quality assurance teams use to evaluate recorded customer interactions against operational, compliance, and communication standards. While traditional BPOs rely on random manual sampling, modern operations implement automated AI call scoring to eliminate auditor bias and achieve complete operational compliance.

The 5 Steps of a Traditional BPO Call Audit

Step 1: Interaction Sampling — Selecting random call recordings from the telephony PBX (typically 3 to 5 calls per agent per month).

Step 2: Scorecard Evaluation — Auditing calls against standardized metrics using a call QA scorecard template.

Step 3: Calibration Sessions — Bringing QA managers together to align on scoring standards and eliminate individual auditor bias.

Step 4: Agent Feedback & Coaching — Reviewing flagged recordings with agents to correct script deviations.

Step 5: Trend Analysis & Reporting — Aggregating floor-wide data to detect recurring training gaps.

Why BPOs Are Moving to 100% Automated Call Audits

Manual sampling leaves 97% of calls completely unreviewed, meaning regulatory violations and customer churn risks go unnoticed until an escalation occurs.

Deploying AI allows contact centers to execute a true 100% call audit policy, scoring every conversation within minutes of completion and alerting QA leads to compliance failures instantly.

Frequently Asked Questions

What is call calibration in a BPO?

Call calibration is a regular session where QA evaluators, team leads, and operations managers score the same call independently to align their scoring criteria and eliminate grading variance.
