Devotel Orbit Voice AI Agents
What are Devotel Orbit Voice AI Agents?
Devotel Orbit Voice AI Agents is a platform for building and running real-time AI voice agents that answer, reason over your knowledge base and live systems, and speak back on a phone call — the infrastructure to build an AI voice agent platform without assembling speech-to-text, an LLM, text-to-speech, and telephony from separate vendors yourself. Devotel Orbit runs the agent runtime and the voice AI agent infrastructure end to end: a low-latency streaming pipeline, tool calling against your own systems, and calls carried on Devotel's own carrier-of-record wholesale softswitch — alongside SMS, WhatsApp, RCS, email, and a human contact center on one platform and one pay-as-you-go bill.
Orbit publishes its per-stage voice-agent latency SLO budget openly: a 1,100ms p50 / 1,500ms p95 turn-latency target across endpointing, speech-to-text, LLM reasoning, and text-to-speech (next benchmark review scheduled for November 6, 2026) — a committed target other AI-voice-agent vendors don't publish at all. See the full latency benchmark.
How a Devotel Orbit voice AI agent call works
1. Call reaches the carrier-of-record softswitch
An inbound call lands on Devotel's own wholesale softswitch — the carrier of record — or an outbound call originates from it; either way the media path never depends on a third-party call-control API.
2. Audio streams into the agent runtime
The call is bridged to Orbit's agent runtime over a low-latency media path, where speech-to-text transcribes the caller's audio in real time with partial results streamed as the caller speaks.
3. The LLM reasons with tools and knowledge
The reasoning layer decides what to say and what to do next, grounded in your knowledge base and able to call registered tools against your own systems (look up an order, check a slot, create a ticket).
4. Text-to-speech responds, with barge-in
The response is synthesized back into natural-sounding audio and streamed to the caller; the caller can interrupt at any point and the agent yields the turn instead of talking over them.
5. Quality scoring, synthesis, and handoff run alongside
The Voice AI Quality Index scores the call as it happens, a post-call step writes a summary and action items the moment the call ends, and the agent can hand off to a human or another specialist agent with the transcript attached.
What Devotel Orbit Voice AI Agents includes
| Capability | What you get |
|---|---|
| Real-time streaming voice pipeline | Speech-to-text, an LLM reasoning layer, and text-to-speech run as a real-time streaming loop targeting about a second per conversational turn, with barge-in so a caller can interrupt the agent mid-sentence. |
| Native agent runtime with tool calling | Agents call your own systems mid-call through a registered tool catalog (HMAC-signed, JSON-Schema validated), and a published MCP server exposes the same platform to external agent tooling — no separate bot framework to wire up. |
| Knowledge-base grounded answers | Agents answer from your uploaded documents and business rules through retrieval, with per-tenant knowledge isolation, so responses stay grounded in your content instead of the model's general knowledge. |
| Voice AI Quality Index | Every call is scored 0–100 in real time on response latency, interruption rate, and caller sentiment, so a degrading call surfaces before a customer complains. |
| Automatic post-call synthesis | The moment a call ends, Orbit writes a summary, action items, an overall sentiment read, and the topics that came up to the call record and pushes them to your webhooks. |
| Squad handoff with cross-call memory | An agent can transfer a caller to a specialist mid-call with a context note before the specialist speaks, and agents recall a contact's prior call summaries so a returning caller does not repeat themselves. |
| Carrier-of-record termination | Inbound and outbound calls run on Devotel's own wholesale softswitch connecting to 500+ global voice aggregators and mobile network operators — not a resold trunk chain — so one accountable owner controls routing, caller ID, and call quality end to end. |
| Human handoff to the same inbox | An agent escalates to a human with the full transcript attached, in the same shared inbox that handles SMS, WhatsApp, RCS, and email — no separate contact-center tool to bridge. |
Example call flows
Inbound support triage
The agent answers first, resolves account and order questions from your knowledge base, and hands off the calls that need judgment — with the transcript already attached for the human agent.
Appointment scheduling
The agent checks availability through a registered tool call, books the slot, and confirms it over SMS or RCS to the same contact — same account, same conversation history.
Lead qualification
Inbound calls are qualified and scored against your criteria before a human sales rep steps in, with a post-call summary and sentiment read waiting in the CRM the moment the call ends.
After-hours coverage
The agent covers calls outside business hours, answering what it can from the knowledge base and queuing an escalation with full context for the next available human shift.

Voice AI agents — frequently asked
- What is an AI voice agent?
- An AI voice agent is software that answers a phone call, understands free speech in real time, reasons over the caller's context, and talks back — instead of navigating callers through a fixed 'press 1' phone menu. Modern contact centers use one for routine inbound and outbound calls and escalate the calls that need a human, with the transcript attached. Devotel Orbit is a platform for building and running those agents — the details are below.
- What role do AI voice agents play in modern contact centers?
- In a modern contact center, an AI voice agent is the first point of contact on routine calls: it answers instantly, resolves the questions it can from the knowledge base, and hands the calls that need a human to the same shared inbox — with the full transcript attached — so human agents spend their time on the calls that actually need judgment. On Devotel Orbit that handoff runs through the same platform as the rest of the contact center, across voice, SMS, WhatsApp, RCS, and email.
- What are Devotel Orbit Voice AI Agents?
- Devotel Orbit Voice AI Agents are real-time AI phone agents that listen, reason over your knowledge base and live systems, and speak back on a call — built on a streaming speech-to-text, LLM, and text-to-speech pipeline, with calls carried on Devotel's own carrier-of-record wholesale softswitch.
- How do I build an AI voice agent platform on Devotel Orbit?
- You configure an agent once — its knowledge base, tool calls, and human-handoff rules — inside Orbit's dashboard or API, and deploy it on inbound and outbound calls without assembling speech-to-text, an LLM, text-to-speech, and telephony from separate vendors yourself. The same agent also runs across SMS, WhatsApp, RCS, and email from the same configuration.
- What infrastructure powers Devotel Orbit's AI voice agent platform?
- A low-latency streaming pipeline (speech-to-text, an LLM reasoning layer with tool calling, and text-to-speech) bridged to Devotel's own carrier-of-record softswitch — not a resold trunk chain — plus a native agent runtime with a published MCP server and knowledge-base retrieval, so the whole voice AI agent infrastructure runs on one accountable platform.
- How does Devotel Orbit compare to Vapi and Retell AI for voice AI agents?
- Vapi and Retell AI are focused voice-AI specialists — voice is the whole product, and neither publishes a per-stage voice-agent latency benchmark. Devotel Orbit builds the same class of real-time voice agent on a streaming pipeline with a Voice AI Quality Index and automatic post-call synthesis, then adds SMS, WhatsApp, RCS, email, and a human contact center on the same platform and one pay-as-you-go bill, terminated on Devotel's own carrier-of-record network rather than a bring-your-own telephony vendor.
- Can a Devotel Orbit voice AI agent hand off to a human?
- Yes. An agent escalates to a human with the full call transcript attached, landing in the same shared inbox that already handles SMS, WhatsApp, RCS, and email — so a customer never repeats themselves.
- What do I need to know before implementing voice AI agents?
- Four things decide whether a first voice AI agent succeeds: what it answers from (ground it in your real help content and business rules, not the model's general knowledge), what it can do (register the specific tools it may call mid-call — look up an order, book a slot — rather than a generic webhook), where it escalates (define when a call goes to a human and make sure the transcript travels with it), and how fast each turn is (several seconds of dead air breaks the conversation; ask any vendor for a published per-turn latency target, not a marketed average — Orbit publishes a 1,100ms p50 target openly). On Orbit those four are one agent configuration — knowledge base, tool registry, handoff rules, and a published latency target — deployed on inbound and outbound calls from the same setup.
- Does Devotel Orbit support outbound AI voice calls?
- Yes. Outbound AI voice agent calls, like all outbound voice on the platform, are carried over Devotel's own wholesale carrier-of-record softswitch rather than a third-party call-control API, so routing, caller ID, and call quality stay under one accountable owner end to end.
- Can a voice AI agent call my own systems mid-call?
- Yes, through a registered tool catalog — HMAC-signed and JSON-Schema validated — that lets an agent look up an order, check availability, or create a ticket while the call is in progress, and a published MCP server exposes the same tool-calling surface to external agent tooling.
