WHY VOICE AI

Automate Inbound Calls with Whatsapp AI Agents

Synthflow’s AI Agents eliminate missed calls and manual routing by integrating directly with your Whatsapp Business Account. Agents deliver fast, accurate responses and consistent customer experiences — at scale, without adding staff.
24/7 Availability
Synthflow agents answer every call instantly — no hold queues, no missed calls. They greet callers naturally, capture intent, and route or assist in real time.
Human-Like Conversations
Unlike IVRs or chatbots, voice AI understands intent and context — it can handle interruptions, clarify questions, and maintain a friendly, natural tone.
Agents that Take Action
Synthflow Agents don’t just talk — they act. They can book appointments, update CRM records, send confirmations, or transfer urgent calls — all in one flow.

HOW IT WORKS

Launch an AI Receptionist in 4 Simple Steps

The BELL Framework powers every Synthflow deployment — from designing your first AI receptionist to scaling complex, multi-agent systems. It connects every stage of the process — Build, Evaluate, Launch, and Learn — so you can create, test, and optimize voice agents in one seamless, no-code environment.
BUILD

Design Voice Flows

Use the no-code builder to map logic, set variables, and define call behaviors. Every prompt, path, and action is fully controlled — so agents act predictably, every time.

EVALUATE

Simulate Real Calls

Test every agent automatically. Simulated calls measure accuracy, response quality, and compliance against your KPIs, ensuring performance before calls go live.

LAUNCH

Deploy with Guaranteed Reliability

Deploy your agent through secure telephony integrations or APIs. Built-in observability and low-latency infrastructure ensure every call connects smoothly and performs at scale.

LEARN

Monitor and Improve

Once live, Auto-QA and monitoring analyze every conversation in real-time. Insights on accuracy and intent feed back into the next version — so agents improve continuously.
