Call auditing
Definition
Call auditing
Call auditing is the review of recorded customer calls against a set scorecard. It scores agent skill, compliance, and customer experience, then feeds what it finds into coaching and process fixes. A call audit turns talk into evidence you can act on.
Audits stopped being an HR formality years ago. Grand View Research sizes contact center software in the billions of dollars, and buyer demand for AI-driven quality dashboards has climbed steadily since 2022.
Two things changed the work recently. Analytics made full call coverage cheap, and regulators now ask to see the audit trail itself rather than a tidy summary written after the fact.
If your BPO partner cannot show you exactly how a call gets scored, you cannot prove the program is working. Buyers who ask for the scorecard before signing get cleaner data and far fewer surprises at the quarterly business review.
Key takeaways
- A call audit scores sampled conversations on greeting, compliance, accuracy, soft skills, and resolution.
- Most BPO contact centers audit 2–5% of monthly call volume per agent to control calibration cost.
- AI speech analytics now scores every call, with human auditors calibrating the model on edge cases.
- Compliance scoring is non-negotiable for outsourced campaigns running in regulated industries.
- Weekly calibration keeps auditor scores close together, which is what makes the trend data usable.
How it works
A call audit runs a five step loop: define the scorecard, sample the calls, score them, calibrate the scorers, then act on the data. Every criterion should tie to a business outcome rather than a personal preference.
The scorecard is the heart of the program — every line item ties back to compliance, retention, or sales close rate. Criteria nobody can act on get cut at the next review.
Most contact centers blend three audit modes. Manual quality assurance pulls a random sample of calls and scores each one by hand against the rubric.
Automated quality assurance uses speech analytics platforms such as CallMiner, Observe.AI, or NICE Enlighten to score every call on keywords, silence, and sentiment.
Hybrid quality assurance is where most 2026 programs land. The model flags risky calls, and human auditors spend their hours on the small share that genuinely needs eyes, instead of a random sample that mostly confirms what you already knew.
Typical scorecard weighting
| Criterion | Weight | What it checks |
|---|---|---|
| Compliance and disclosure | 25% | Mini-Miranda, card handling, recording consent |
| First call resolution | 20% | Issue closed without a 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 | 5% | Offer presented, objection handled |
| Data handling and privacy | 5% | Masking, screen capture, retention rules |
Calibration is where most programs quietly fail. If three auditors score the same call 95, 78, and 64, the data is noise. Weekly calibration sessions align scorers on edge cases and tighten the wording in the rubric.
Review the scorecard itself twice a year at minimum. Products change and disclosure scripts change, so a criterion that earned its place in 2024 can be dead weight on the form by 2026.
Examples
Auditing looks different in banking, telecoms, and outsourced delivery, but the pattern repeats. Regulators set the compliance lines, analytics sets the coverage, and calibration decides whether anyone inside the business trusts the resulting score.
In January 2024, JPMorgan Chase agreed to pay USD 18 million to settle United States Securities and Exchange Commission claims over client agreements that discouraged whistleblower reports.
Documented records are what regulators ask for first — not what an internal review turns up later. Banks now audit their consent and retention lines as closely as they audit agent tone.
Telstra, Australia’s largest telco, reworked quality assurance across its Philippine contact centers in 2022 after moving to cloud analytics. The team stopped sampling a flat 3% of calls and started reviewing the calls the model had flagged red.
Concentrix, a Manila and Cebu employer of more than 70,000 Philippine agents, certifies campaigns against ISO 18295, the contact center standard published by ISO in 2017 and still named in requests for proposal today.
Smaller offshore providers start simpler — a spreadsheet scorecard plus a call recording platform — then graduate to a full quality assurance suite once monthly volume passes roughly 50,000 calls.
Healthcare and collections campaigns weight the form differently again, pushing consent capture and disclosure wording well above tone, because one missed disclosure can put the whole account at risk.
Ask any shortlisted vendor for three scored calls from last quarter with the auditor comments intact. A partner running a real program produces them within a day.
Related terms
These are the entries buyers most often confuse with call auditing. Knowing what separates each one makes vendor proposals much easier to read, because providers use the labels loosely and price the work very differently.
- Call center: the operational unit being audited, with quality assurance sitting inside or beside it.
- Quality assurance: the broader discipline, of which call auditing is the contact center flavour.
- Customer satisfaction (CSAT): the headline metric most audit programs ultimately serve.
- First call resolution: a near universal scorecard line item covering issues closed without a callback.
- Service level agreement: the contract clause setting quality thresholds an outsourced vendor must hit.
- Speech analytics: the technology layer powering automated auditing at scale.
- Compliance: the regulatory floor every audit checks against.
FAQ
How many calls should you audit per agent?
Manual programs typically review 4 to 10 calls per agent each month, while speech analytics pushes coverage to every call. Size the sample against monthly volume, not a flat number. New hires and agents on a coaching plan belong at the top of that range.
Who should run the call audit?
A dedicated quality analyst outside the line management chain should own scoring and calibration. Outsourced contact centers usually staff roughly one analyst per 25 agents, with the client’s own team spot checking a handful of scored calls 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 calls against a rubric, producing trend data that feeds training plans and contract reviews. Mature programs run both.
How does AI change call auditing?
Speech analytics scores every call on keywords, sentiment, and silence, then surfaces the outliers for human review. Gartner has forecast that conversational AI will strip billions from contact center labor costs by 2026, moving spend from headcount to model tuning.
Is call auditing required by law?
In financial services, healthcare, insurance, and debt collection, regulators expect documented quality programs covering recording consent, disclosure scripts, and data handling. The Payment Card Industry Data Security Standard (PCI DSS) assumes an audit trail exists.
What does a call audit cost when outsourced?
Bundled into BPO pricing, quality assurance typically adds 6 to 12% to a per hour seat rate.
