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.
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 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.
- 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.
