THE PROBLEM

You're Shipping Blind.
Your Clients Pay the Price.

Real callers are nothing like your test calls. Here's what happens on the calls you never hear.

🧠

Hallucinated Pricing

Your agent invents service packages and quotes random numbers. One wrong price kills trust instantly. Your client finds out from their customer, not from you.

Avg cost: $800/deal lost to wrong pricing
🔇

Silence Death Spirals

Caller goes quiet for 5 seconds. Agent panics — repeats itself, asks the same question, or just hangs up. The lead is gone and you never know why.

Avg cost: 23% of calls end in silence drops
💬

Memory Wipes Mid-Call

Caller corrects their name on turn 2. By turn 6, agent uses the wrong name. Asks for the timezone twice. Forgets the appointment. Trust destroyed.

Avg cost: 41% drop in booking rate
Every broken call is a lost deal. The average voice AI agency loses $2,400/month per client to undetected agent failures.
