Call auditing
Definition
Call auditing
Call auditing is the structured review of recorded customer calls against a defined scorecard, measuring agent performance, compliance, and customer experience. You sample live and recorded conversations, score them on quality criteria, and feed the findings straight back into coaching, training, and process improvements that lift first-call resolution and CSAT.
Key takeaways
- A call audit scores sampled conversations against weighted criteria covering greeting, compliance, accuracy, soft skills, and resolution.
- Most BPO contact centers audit 2–5% of monthly call volume per agent, balancing coverage with calibration cost.
- AI speech analytics now lets QA teams score 100% of calls automatically, with humans calibrating the model on edge cases.
- The 2023 introduction of FCC stricter robocall rules and ongoing PCI DSS scope make compliance scoring non-negotiable for outsourced campaigns.
Audits are no longer an HR formality. The contact center software market reached USD 47.2 billion in 2024 according to Grand View Research, and the share of buyers asking for AI-driven QA dashboards has climbed every quarter since 2022. If your BPO partner cannot show you how a call gets scored, you cannot prove the program is working.
How it works
A call audit follows a five-step loop: define the scorecard, sample the calls, score them, calibrate the scorers, and act on the data. The scorecard is the heart of the program — every criterion ties to a business outcome such as compliance, retention, or sales close rate.
Most contact centers blend three audit modes. Manual QA pulls a random sample and scores it on a rubric. Automated QA uses speech analytics platforms like CallMiner, Observe.AI, or NICE Enlighten to score every call against keywords, silence, and sentiment. Hybrid QA lets the machine flag risky calls so human auditors spend their time on the 5% that actually need eyes.
Typical scorecard weighting
| Criterion | Weight | What it checks |
|---|---|---|
| Compliance and disclosure | 25% | Mini-Miranda, PCI handling, recording consent |
| First-call resolution | 20% | Issue closed without callback |
| Accuracy of information | 20% | Correct policy, pricing, or product detail |
| Soft skills and empathy | 15% | Tone, active listening, hold etiquette |
| Process adherence | 10% | CRM notes, after-call work logged |
| Sales or upsell execution | 10% | Offer presented, objection handled |
Calibration sessions are where most programs fail. If three auditors score the same call 95, 78, and 64, the data is noise. Teams run weekly calibration meetings to align on edge cases and tighten the rubric.
Examples
In 2023, JPMorgan Chase agreed to pay USD 18 million over allegations that its retail brokerage failed to record calls properly — a textbook reminder that recording gaps surface during regulator audits, not internal ones. Banks now audit retention compliance, not just agent tone.
Telstra, Australia’s largest telco, restructured its Philippine call center QA in 2022 after rolling out NICE CXone analytics, which scored 100% of inbound calls and cut average handle time by 11% in the first year. The QA team shifted from sampling 3% of calls to auditing only the 5% that the model flagged red.
Concentrix, a Manila and Cebu BPO employer of more than 70,000 agents in the Philippines, publishes its QA framework annually and uses calibrated audits to certify campaigns against ISO 18295 contact center standards, the international benchmark published by ISO in 2017 and still cited in RFPs today.
Smaller Source Boost partners often start with a simpler stack, such as Google Sheets scorecards plus a recording platform like CallRail, before graduating to a full QA suite once monthly volume passes 50,000 calls.

FAQ
How many calls should you audit per agent?
Industry practice ranges from 4 to 10 calls per agent per month for manual QA, or 100% of calls when speech analytics is in place. Sample size should be statistically valid for the agent’s monthly volume, not a flat number.
Who should run the call audit?
A dedicated QA analyst, ideally outside the line-management chain, runs scoring and calibration. Outsourced contact centers usually staff a QA pod at roughly one analyst per 25 agents, with client-side QA spot-checking monthly.
What is the difference between call auditing and call monitoring?
Call monitoring is live listening for coaching in the moment. Call auditing is the systematic scoring of sampled or recorded calls against a rubric, producing trend data that feeds training plans and contract reviews.
How does AI change call auditing?
AI speech analytics scores every call automatically on keywords, sentiment, and silence, then surfaces outliers for human review. According to Gartner, conversational AI will cut global contact center labor costs by USD 80 billion by 2026, shifting QA spend from headcount to model tuning.
Is call auditing required by law?
For regulated industries — financial services, healthcare, debt collection, insurance — yes, regulators expect documented QA programs covering recording consent, disclosure scripts, and data handling. PCI DSS, HIPAA, and the FCC’s TCPA framework all assume an audit trail exists.
What does a call audit cost when outsourced?
Bundled into BPO pricing, QA typically adds 6 to 12% to a per-hour seat rate. Standalone QA-as-a-service runs USD 2 to USD 6 per audited call in 2024, depending on language and depth.
