Voice Agents
Inbound and outbound phone agents on Vapi, Retell, or Bland — grounded in your data, taking real actions, not reading a brittle script.
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.

- ✓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

Why us
Why us.
Nous is channel-agnostic — voice is just another channel on the same grounded engine, so the agent knows your data, not 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.
