Inbound Voice Agents
Answer inbound calls, route, take a message, or handle the call end-to-end.
AI Agents
Voice AI agents that answer and place calls with sub-second turn-taking — the speech-to-text, the language model, the text-to-speech, the telephony, the eval suite and the audit log that make a voice agent safe enough to put in front of a customer.

Overview
A voice AI agent is a member of the team that picks up the phone. The work is the speech-to-text, the language model, the text-to-speech, the telephony, the turn-taking, the barge-in, the hold, the transfer, the audit log. The phone call is the product, and every part of it has to be engineered.
We build voice AI agents with the telephony, the STT, the LLM, the TTS, the eval suite and the audit log as part of the architecture from sprint one. The output is a voice agent that handles the call, not a demo that works once and then breaks on the second call.
This is the wrong engagement if the call volume does not justify the build. Voice agents are a serious investment, and the right answer for a low-volume use case is a human team or a simple IVR.
What we deliver
Answer inbound calls, route, take a message, or handle the call end-to-end.
Place outbound calls — reminders, confirmations, follow-ups — with the eval that proves it.
Twilio, Exotel, Plivo, the telephony that connects the agent to the phone network.
Speech-to-text, the language model, text-to-speech — the voice pipeline engineered end-to-end.
Sub-second turn-taking, barge-in, hold, transfer — the conversation dynamics.
Every call logged, every action auditable, with the eval the QA team can act on.
Our process
01
Discover
We agree the use case, the call flow, the telephony and the escalation criteria.
02
Plan & Design
We design the agent, the telephony, the pipeline and the eval suite.
03
Develop
We build in two-week sprints with the QA team testing as we go.
04
Deploy
We ship to production with the telephony, the eval and the audit log live.
05
Optimize & Grow
We read the resolution rate, the eval and the QA feedback.
Technology
What you can expect
Industries we serve
When the pipeline is engineered. We use a high-quality TTS (ElevenLabs, Cartesia, OpenAI) with the voice that matches the brand. The eval suite includes a voice quality test, and the QA team reviews the calls weekly. The agent sounds like a person, not a robot, because the pipeline is right.
The conversation dynamics are part of the architecture. Barge-in (the caller interrupts the agent), hold (the agent puts the caller on hold), transfer (the agent transfers to a human) — all engineered, all tested, all in the eval suite. The conversation feels like a conversation because the dynamics are right.
A clear escalation path, with the criteria, the context the human needs, and the call record that follows the case. The agent transfers when the case is genuinely complex, the human picks up with the context, and the resolution time drops. The escalation is the most important part of the system.
Yes. The voice pipeline runs against Twilio, Exotel, Plivo, Vonage or your existing PBX, with the deployment model agreed in the discovery. The eval suite runs against the real telephony, not a mock, and the QA team reviews the real calls.
