An inbound voice agent for high-volume scheduling

We built an inbound voice agent that handles routine scheduling calls and hands off cleanly to staff when a call needs a person, so fewer bookings are lost at peak times.

Illustrative example. Named engagements are shared with client permission.

01

Context

A field services company missed calls during busy periods, and every missed call was a lost booking. Staff could not keep up with routine scheduling requests at peak.

02

Challenge

Missed and abandoned calls were losing bookings during peak hours.

03

Product approach

We designed the conversation and escalation paths first, then orchestrated speech recognition, reasoning, and speech synthesis for low latency and wired the agent into the existing scheduling and CRM systems.

Engineering decisions

Latency budget first

We set a strict latency budget and streamed every stage, because a slow voice agent loses callers regardless of how well it reasons.

Escalation as a first-class path

The agent hands off to a person with context whenever a call falls outside routine scheduling, rather than forcing a resolution.

08

Responsible AI and safeguards

  • Clear handoff to a person when the agent cannot help
  • Guardrails on what the agent can commit to
  • Call analytics for review and improvement
  • No irreversible action without confirmation
09

Outcome

  • Fewer missed and abandoned calls at peak
  • Routine scheduling handled without staff time
  • Clean escalation preserved the caller experience

Lessons

  • Latency is the difference between a voice agent people use and one they hang up on.
  • Escalation is a feature: knowing when to hand off builds trust.
  • Integrating with the real scheduling stack mattered more than conversational polish.
