Ruby and Smith.ai charge $2+ per minute from the very first call. Run a marketing campaign that doubles your call volume? Your answering service bill doubles too.
Vox plans include 1,000–2,000 minutes at a predictable base rate. Even if you go over, overages are just $0.35/min — still 80%+ cheaper than human answering services. Your costs stay predictable, and even at peak volume you save thousands compared to per-minute billing.
When Ruby or Smith.ai operators are busy, your caller waits. 15 seconds. 25 seconds. Maybe 40. Call abandonment rates spike 300% after 20 seconds of hold time.3
Vox answers in under 1 second. Every time. Whether it's handling 1 call or 50 simultaneously.
Ruby employs ~800 receptionists.4 Smith.ai employs a few hundred. These are real people who call in sick, need training, take vacations, and have capacity limits.
Vox is software. It scales horizontally. When your business grows from 100 calls/month to 1,000, Vox doesn't need to hire anyone. Your service quality doesn't degrade. And even at peak volume, Vox costs a fraction of what human services charge.
Let's address this directly.
Vox uses advanced conversational AI that adapts to your brand voice. Is it identical to a human? No. Is it better than the average answering service operator handling calls for 30 different companies simultaneously? Yes.
Vox handles 85–90% of inbound calls end-to-end. For the remaining 10–15% that require human judgment, Vox warm-transfers to your team with full context.
Vox doesn't mishear names, misspell email addresses, or forget to ask qualifying questions. Human operators average a 12–15% error rate on intake data entry.5 Vox's error rate is near zero.
Port your existing answering service number or set up call forwarding. Most businesses are live within 5 minutes.
