Average Speed of Answer (ASA)

Average speed of answer, or ASA, is the mean number of seconds a caller waits in queue before a live agent picks up. Contact centers report it in seconds, and it sits at the top of most service level agreement sheets.

Low ASA means calm customers. High ASA means abandoned calls, angry escalations, and a service target that slips out of compliance — often before the shift is half over.

Most centers time ASA from the moment the phone menu ends to the moment the agent’s headset opens the line. Phone-system logs and CRM dashboards often disagree, so aligning both feeds is the first fix teams try.

The metric doubles as an operational and financial lever. Faster answers cut abandonment, protect satisfaction scores, and pull more revenue through the queue. That is why it appears in almost every outsourcing contract as a billable threshold.

Key takeaways

• ASA reports the mean wait between queue entry and agent pickup, measured in seconds.
• A common industry target is answering 80% of calls inside 20 seconds, roughly a 28-second ASA.
• ASA correlates strongly with abandonment rate, customer satisfaction, and SLA compliance.
• Staffing, forecasting, and menu design are the three biggest levers for improving it.
• Offshore teams in the Philippines and India often beat onshore ASA benchmarks at a fraction of the cost.

How it works

ASA is calculated by adding every caller’s wait time inside the queue, then dividing by the total number of answered calls. Abandoned calls are excluded, because there was no agent pickup to time against. The result is one clean benchmark number.

The formula: ASA = total wait time of answered calls ÷ total answered calls

One warning about that denominator. Because abandoned calls drop out, a queue with heavy abandonment can post a flattering ASA while its worst-served callers never appear in the number at all.

Most contact center platforms compute ASA automatically. Genesys, NICE, Five9 — all three split the figure by queue, skill and shift, so analysts can see exactly where the wait accumulates.

Pair ASA with abandonment rate and service level agreement attainment. Read together, those three numbers tell you whether a slow queue is a staffing problem or a routing problem, and the two are fixed in very different ways.

Here is a benchmark table drawn from contact center reports circulated in 2024. The gap column is the one worth reading.

Healthcare runs 73% over its own published target and telecommunications 51% over. Retail sits 70% above target despite carrying the tightest goal on the board, which tells you the published benchmark and the lived reality have drifted apart.

Where actual ASA drifts above target, the fix is rarely one lever. Teams tune queue management rules and rebuild rosters against forecast intraday volumes.

A well-designed interactive voice response (IVR) menu shaves 10 to 20 seconds off ASA by resolving simple questions before they ever reach the queue.

Staffing math drives the rest. Erlang C models translate forecast volume into required agent hours, so a forecasting miss shows up in ASA long before it shows up in any monthly report.

Examples

Every ASA improvement story follows the same arc: a bad number, a root-cause hunt, then a targeted fix. Outsourcing shows up in most of them because Filipino and Indian centers pair tight forecasting with generous 24/7 rosters.

A US retail bank flagged an ASA of 92 seconds in Q2 2024, well above its 30-second contractual target. It moved overflow to a Manila-based partner sourced through Clutch’s BPO directory.

Blended ASA dropped to 24 seconds within two quarters, a 74% improvement. The domestic team kept complex escalations while the offshore call center absorbed volume peaks. Agent count grew 40% — cost per call fell 55%.

An Australian telco added a Filipino BPO for Tier-1 support in 2023. The partner belongs to the IT & Business Process Association of the Philippines, the peak body behind the country’s IT-BPM industry roadmap.

ASA fell from 71 seconds to 34 seconds inside six months, a 52% cut, and customer satisfaction climbed 11 points. The BPO staffed a dedicated evening bank rather than stretching the existing roster across more hours.

A UK health-tech scale-up moved its patient-support desk to a Cebu-based provider late in 2023. Follow-the-sun coverage plus stronger forecasting halved ASA during the evening peak, the window where its queue had always broken down.

That provider bills against ASA thresholds rather than a flat FTE rate, so incentives stay aligned. Contracts written that way make ASA a key performance indicator (KPI) with money attached.

Across all three cases, ASA moved for the same reason: capacity finally arrived in the hours the volume actually landed. None of them bought a new phone system to get there.

ASA sits inside a cluster of contact center metrics and disciplines. Each term below either feeds ASA, contains it, or gets confused with it — so knowing where the boundaries fall makes benchmark conversations much shorter.

• Key Performance Indicator (KPI): the broader class of measures ASA belongs to.
• Service Level Agreement: the contractual thresholds, often 80/20, that ASA rolls up into.
• Queue Management: the routing and prioritization discipline that moves ASA most directly.
• Interactive Voice Response (IVR): the self-service front door that absorbs queries before they reach an agent.
• Call Center: the operational unit where ASA is measured and managed.
• Customer Service: the wider practice ASA sits inside, alongside half a dozen headline metrics.

FAQ

These are the ASA questions that surface most often in vendor reviews and quarterly business reviews. Each answer is short on purpose, because ASA disputes usually turn on definitions rather than on the data itself.

What is a good average speed of answer?

Most contact centers aim for 20 to 30 seconds, usually stated as 80% of calls answered inside 20 seconds. Anything above 60 seconds signals a staffing or routing gap.

How is ASA different from average handle time?

ASA measures the wait before an agent connects. Average handle time (AHT) measures how long that agent then spends on the call. Both matter, but different levers move them.

Does offshoring improve ASA?

Yes, when it is done well. Offshore partners in the Philippines and India commonly hit 15 to 25 second ASA on well-forecast queues. Precedence Research’s BPO market report puts the global BPO market at USD 347.95 billion in 2025.

What causes a sudden spike in ASA?

Common triggers are unexpected volume from an outage or a campaign launch, agent absenteeism, and misconfigured menus that dump too many callers into one queue. Check intraday forecast variance first, since it explains most spikes within minutes.

Can automation help lower ASA?

Yes: smart routing, chat deflection and voice bots triage a growing share of customer service contacts before they ever queue for a human, so centers that pair automation with good forecasting routinely cut ASA by 30 to 40%.
