AI voice agents that answer the phone, handle routine calls and know when to transfer.

We build spoken-language agents for inbound calls — scheduling, routing, intake and common questions — tuned for natural turn-taking, interruptions and noisy lines, with consent, call recording rules and human handoff designed in.

What we deliver
  • Call flow and script design
  • Speech pipeline
  • Telephony integration
  • Scheduling and system connections
  • Consent, recording and disclosure
  • Call analytics and review

Where this helps

Calls go unanswered
After hours, at lunch or during a rush, callers reach voicemail or hang up. Each missed call may be a missed booking or an unhappy customer.
Phone menus that callers hate
Touch-tone menus force callers to guess which option fits their problem, and many simply press zero or give up.
Skilled staff tied to the phone
Receptionists and coordinators spend much of the day on routine scheduling and questions instead of work that needs their judgment.

What we deliver

01
Call flow and script design
The call types the agent handles, what it asks, how it confirms details aloud, and exactly when it transfers or takes a message.
02
Speech pipeline
Speech recognition, language model and text-to-speech tuned for your callers' accents and vocabulary, with low response delay and natural voices.
03
Telephony integration
Connection to your phone numbers, call routing and existing phone system, including warm transfer to staff with a spoken or on-screen summary.
04
Scheduling and system connections
Real-time lookups and bookings in your calendar, practice management, CRM or reservation systems.
05
Consent, recording and disclosure
Caller disclosure that they are speaking with an AI, recording notices and retention rules that match the jurisdictions you operate in.
06
Call analytics and review
Transcripts, outcomes, transfer reasons and flagged calls for quality review, searchable by your team.

How it works

  1. 01

    Listen to real calls

    We review recordings or call logs to map the most common call types, how callers phrase requests and where calls go wrong today.

  2. 02

    Design the call flows

    Flows, confirmations and transfer rules are agreed with the people who answer the phone now.

  3. 03

    Build and voice-test

    The agent is built and tested with scripted and unscripted calls, including accents, background noise and interruptions.

  4. 04

    Staged go-live

    Start with overflow or after-hours calls, with staff reviewing transcripts, before taking on more of the call volume.

  5. 05

    Tune and extend

    Adjust recognition, prompts and flows from real calls, then add new call types one at a time.

Design decisions we make with you

  • Latency and turn-taking

    Callers notice pauses. We choose models and streaming strategies that keep responses quick and let callers interrupt naturally.

  • What the agent will not do

    Emergencies, complaints, payment details and sensitive topics can route directly to a person or a dedicated line.

  • Transfer design

    Warm transfer with context, callback scheduling or message-taking — decided per call type and by staff availability.

  • Voice and identity

    A clear, consistent voice that identifies itself as automated. We do not clone real people's voices without their explicit consent.

  • Voice versus text

    Voice requires different design from chat — shorter turns, spoken confirmations, no links. For text channels see [AI Chatbots](/ai-services/ai-chatbots).

Questions buyers ask

Yes. We design the agent to disclose that it is automated at the start of the call, and callers can ask for a person at any time.

It transfers to a person with a summary of the call, schedules a callback, or takes a detailed message — whichever you choose for that call type.

Usually. We connect through SIP or cloud telephony providers, and can forward specific numbers or overflow calls to the agent without replacing your system.

Rules vary by jurisdiction. We build in disclosure, consent prompts and retention settings, and recommend you confirm requirements with counsel. See trust and security.
