Most businesses know how much they’re paying per minute. Few know their ASR. That’s usually backwards.
ASR stands for Answer Seizure Ratio. It’s the percentage of call attempts that result in an actual connection — a real person answering, not voicemail, not a network error, not a busy signal.
Formula: (answered calls ÷ total call attempts) × 100
If you make 1,000 call attempts and 620 connect — your ASR is 62%.
Why this matters more than per-minute pricing:
Say Provider A charges $0.008/min with 55% ASR.
Provider B charges $0.012/min with 78% ASR.
With Provider A, 450 of your 1,000 attempts fail. You pay for the attempts that connect, waste time on the ones that don’t, and your agents spend a significant part of their day hitting dead ends.
With Provider B, you connect more, your agents talk more, and your cost per successful call is often lower — despite the higher per-minute rate.
A low ASR is usually caused by one of three things:
— Route congestion (especially during peak hours)
— Poor quality contact lists
— Routing to regions where your provider has weak coverage
Check your ASR by hour, by destination, and by day of week. Patterns tell you exactly where the problem is.
