Your AI said 'one moment please' — and the customer heard nothing for 9 minutes

Description and use

AI agents frequently go silent after saying "one moment", causing callers to wait up to 9 minutes and often hang up, leading to lost business. Implementing a silence protocol and recovery scripts reduced the longest silent stretch to 31 seconds and improved callback capture.

Problem

AI phone agents frequently go silent after saying "one moment", causing callers to wait up to 9 minutes and often hang up, leading to lost business.

Outcome

The silence protocol reduced silent stretches, improved caller experience, and captured previously lost callback opportunities, generating measurable revenue.

Workflow

• 1. Identify silent gaps >90s in transcripts. 2. Log cause (tool call, lookup failure, dead transfer). 3. Apply silence protocol rules in the system prompt. 4. Use recovery scripts after gaps. 5. Conduct monthly audit of 50 transcripts with 5 checks. 6. Track metrics on a weekly scorecard.
• 7. Iterate on protocol based on audit results.

Evidence

The agent handled 1,900 calls last month. Average handle time: 2 minutes 40 seconds. Satisfaction tags: fine. But 17% of calls — roughly one in six — contained the same pattern: the AI said some version of "let me check that for you, one moment," went silent, and never came back.

Source

The longest was 9 minutes 12 seconds, after which the caller hung up and called a competitor.

Source

Six weeks after the pest‑control company deployed the protocol: their longest silent stretch that month was 31 seconds (a slow inventory API, filled with two updates), unanswered barge‑ins dropped from 22 per month to 1, and the failed‑lookup callback path caught 38 requests that previously would have evaporated.
