Voice Agents
Inbound and outbound phone agents on Vapi, Retell, or Bland — grounded in your data, taking real actions, not reading a brittle script.
Who builds AI phone agents that can actually book and look things up?
Caffinix builds inbound and outbound voice agents on Vapi, Retell or Bland, backed by a real backend so the agent can look up records, book appointments and update systems instead of reading a script. Latency and human-handoff handling are part of the build, because a voice agent that pauses or traps a caller fails differently from a chatbot.
We build production voice agents that answer calls, book appointments, and take real actions — grounded in your data, not a script that breaks. Telephony on Vapi, Retell, or Bland, with a real backend for tool-calling so the agent can actually look up, book, and update, plus latency and handoff handling so it holds up on a live call.
What you get
- ✓An inbound or outbound phone agent that answers, qualifies, and books — grounded in your data
- ✓Tool-calling into your calendar, CRM, or API so the agent takes real actions, not just talks

Who it's for
- —Clinics, salons, and hotels drowning in booking and reception calls
- —SMBs losing after-hours or overflow calls to voicemail
- —Outbound SDR teams that need qualified, grounded first-touch calls at volume

Why us
Why us.
Nous is surface-agnostic — voice is one more surface on the same grounded engine, so the agent knows your data and can act on it, not read a script.
Real backend depth means telephony, latency, and tool-calling that actually books and looks up — the parts wrappers skip.
Every agent ships with defined refusal behavior and handoff, so it fails safely on the calls it shouldn't handle.
Common questions
Things prospects ask first.
Vapi, Retell, or Bland depending on your latency, telephony, and cost needs. We pick per project rather than forcing one.
Yes — that's the point. We wire tool-calling into your calendar, CRM, or API so the agent takes real actions, not just reads a script.
It hands off to a human on defined rules. We design the refusal and escalation behavior up front, so it doesn't improvise on high-stakes calls.
